Lenovo 3000 N200 (0769)


The Lenovo 3000 N200 (0769) is a decent, functional notebook for both personal and business use, making it a jack of all trades. Although its presentation is a little uninspiring, Lenovo's implementation of Intel's latest Centrino platform gives this machine enough power to comfortably handle a good spread of tasks, which was echoed in our benchmark results.

The N series is specifically targeted at small business users, and it still provides business features, such as a biometric fingerprint scanner and Lenovo's password protection software. However, the N200 also offers some of Lenovo's more personalised features, such as a Webcam and the 15.4in VibrantView wide screen display to provide flexibility for today's hybrid home/business users; its most admirable asset.

At its core is an Intel Core 2 Duo T7300 2.0GHz CPU, 1GB of DDR2 RAM and a GeForce Go 7300 graphics chip. The graphics solution leaves no room for gaming, but the latest Centrino platform (codenamed Santa Rosa) will happily run applications from Adobe Photoshop to Microsoft Office. It will also take care of encoding MP3s fairly quickly, as our tests showed, and making home movies should be a breeze.

Among many new tweaks to the latest CPU, the new Centrino platform offers one very clear advantage over the previous version, an 800MHz front side bus (FSB). Both the CPU bus and the FSB are clocked at 800MHz, giving the new Centrino platform more bandwidth to shuffle data back and forth between the CPU and the memory subsystem.

With its 2.0GHz CPU and 1GB of DDR2 RAM, the Lenovo 3000 N200 reached a total score of 70 in WorldBench 6, about the minimum we'd expect from this new platform. We were particularly impressed by its performance in the MP3 encoding test, generally considered a test of the CPUs performance. Unlike most notebooks with the T7300, which take around 135 seconds to encode 53 minutes worth of WAV files to 192Kbps MP3 files, the Lenovo 3000 N200 took just 128 seconds. We also tested at a higher compression using iTunes, which takes advantage of the multiple cores of the CPU. Compressing 53 minutes of WAV files to 56Kbps MP3 files in iTunes took just 85 seconds.

In our battery tests the N200 performed among the better of the notebooks we've tested recently, while leaving room for improvement. Using a DVD rundown test, a worst case scenario, which impacts maximum drain on the battery by using both the speakers and the optical drive among the other core components such as the CPU, the system lasted for 90 minutes. Under normal workload we expect it to last longer.

For those who like a good movie on the road, the N200 offers a fairly reasonable screen with decent colour, brightness and contrast, with a 1280x800 native resolution. The viewing angle isn't perfect but it will suffice for most peoples needs. The speakers don't produce a very loud sound, but it's clear and a headphone jack is present should the speakers fail to impress you.

For the business or security conscious home user, Lenovo includes its Lenovo Care software, a package that is pre-installed and can be quickly accessed via an associated button on the notebook itself. Lenovo Care gives you quick access to data backups, system maintenance and password protection, as well as network and display profiles and a set of online help links. The interface is easy to read and simple to use.

A total of four USB 2.0 ports are installed, as is one mini FireWire port. Gigabit Ethernet is installed for wired networking, as is 56k modem, while 802.11 a/b/g and draft-n standards are available, not to mention Bluetooth. An Express Card slot joins the list, and a 5-in-1 media card reader is also available. A DVD re-writer with dual layer support and a 120GB hard drive will take care of your storage needs.

Sony VAIO VGN-TZ18GN/X


First Microsoft brought us Readyboost in Vista. Then Intel introduced TurboMemory with Centrino notebooks. Now, finally, the flash memory revolution is complete as one of the last bottlenecks in the PC technology is addressed. Sony's chic ultra portable TZ18GN/X VAIO notebook is our first glimpse at a notebook running solely on a solid-state drive (SSD), rather than the long standing hard drives (HDD) that have been our only option for so long, and it's about time.

Features

The VGN-TZ18GN/X offers a tiny 11.1in screen with a 1366 x 768 resolution and weighs in at just 1.15kg without its power supply (1.5kg with it). It has an Intel Core 2 Duo U7600 ultra low voltage (ULV) CPU running at 1.2GHz, 1GB of DDR2 RAM and the piece de resistance, a 32GB SSD drive as its sole storage device.

Despite the advantages of SSD disks, 32GB is not a lot of storage, especially with 8GB hijacked for a backup and your operating system installed. In fact with all of our testing software installed the drive was verging on full capacity. Fortunately an internal DVD re-writer is installed, which is not only handy for offloading non-essential data, but a reasonable feat for such a small device.

However, we see this system as a solution for frequent travellers with only basic, business style uses for their notebook, such as email, Web surfing and flicking through electronic documents, and in that respect the TZ18GN/X is perfect.

The display is one of the nicer screens available in notebooks, offering good colour, brightness and contrast, as well as an excellent viewing angle. A media card reader supporting MagicGate, MS/MS-Pro and SD cards is installed. Meanwhile a fingerprint reader sits neatly between the mouse buttons and a set of media controls resides on the front edge of the chassis. There's also a VGA camera built into the screen. Watching DVDs was quite pleasant on the screen and the speakers mustered a fair bit of volume for such a small notebook. A set of audio jacks for headphones or a microphone are also available for when the speakers just won't cut it.

Solid-state

Solid-state or non-volatile flash memory and its benefits have been on our doorstep for a long time. Fitness junkies will know to buy a flash-based MP3 player, as it has no moving parts to damage when jogging. Photography enthusiasts will know how many photos can fit on their tiny 4GB memory stick, while speed freaks will know how much faster their PC boots when using Windows Vista's ReadyBoost or Intel's TurboMemory. Let's not forget the convenience of moving data from place to place using USB flash drives, which offer more portability than a 3.5in floppy disk and many times the storage space of some older desktop PCs.

Theoretically flash memory uses less power, emits less heat and is more reliable, not to mention they're less noisy than hard drives or optical drives. As well as being less susceptible to jolts and bumps SSD disks lack the mechanics which, with use, will eventually come grinding to a halt, giving birth to one of those horror stories about data loss we've all heard at some point. None of this comes cheap, which partly explains the hefty price tag.

Benchmarks and battery

The small frame of the VAIO TZ18GN/X makes a clear statement about its raw power; there isn't much. Although the U7600 is a dual core Centrino Duo CPU, it's built for low power consumption and low heat emissions, not speed. We were unable to obtain a score from WorldBench 6, however, the MP3 encoding tests showed just how slow a CPU can go.

Converting 53 minutes of WAV files to 192Kbps MP3 files using Cdex, a single threaded application, took 259 seconds. Using iTunes, a multi-threaded application, to compress the same data to a smaller 56Kbps took 143 seconds. Neither of these scores is impressive by overall comparison, but for a ULV CPU we can't expect much more.

Battery life tests returned far more impressive results. Our Sony TZ18GN/X ultra portable device exhibited excellent battery life, even when compared to other similarly sized ultra low voltage notebooks, such as the Toshiba Portege R500. Using a looping DVD to drain the battery this system lasted just over three hours at 186 minutes; an excellent result.

The DVD loop test is considered a worst-case scenario, as it utilises the optical drive and speakers, as well as the screen, CPU and other core components. Subsequently we expect the system to last longer still when running under normal load. The optical drive can be turned off from the system tray for added power saving.

Design and build quality

Although this unit is rather small it's not overly fragile. The screen does flex a little because it's quite thin, but it isn't overly disconcerting. The main body, which is built from carbon fibre, is sturdy enough and despite the light weight design it doesn't feel too toy-like.

With the exception of the lid, which has a dark brown, brushed metal finish the Sony VAIO TZ18GN/X is a reflective piano black. The keyboard is small, but still comfortable to type on for reasonable length periods of time and the touchpad is nice and responsive.

A pair of USB 2.0 ports joins a VGA out port, an Express Card slot, one gigabit Ethernet port and a 56k modem port on this rather barren chassis. If wired connectivity is not your thing this machine also offers Wi-Fi 802.11 a/b/g and Bluetooth.
