The bad news is that Sony says these sexy 11.1in Vaio TZ laptops are at risk of overheating. But there is something about Sony's Vaio laptops that should make you happy.

From budget laptops to ultra-tiny netbooks, ultraportables and high performance, we explain the tricks to finding out the ultimate laptop at the right price.

Despite some odd feature choices, this is an affordable powerhouse of a laptop. A great value mid-range Centrino 2 laptop, as long as you're not worried about battery life.

Intel’s push on Centrino notebook branding has only made it so far in the six months since its introduction. So far prices have been high for Centrino notebooks, although Emagen looks set to change this mindset, now offering the N1000 model as a cost-effective alternative option to top of the line name brand notebooks with all the bells and whistles.

Speed up your home network with these wireless routers, including faster speeds, better gaming and VoIP handling and automatic security.

Although the mobile marketplace has been changing in the face of Centrino and the slow but gradual tablet PC adoption rate, large form factored (greater than single spindle) notebooks are still the order of the day.

Intel has been banging on about Centrino 2 lately, so it was good to finally get a chance to test the claims courtesy of a spanking new mid-range Centrino 2 M51 Va courtesy of ASUS.

This tiny notebook, measuring a mere 26.5 x 22 x 2.1cm looks quite ordinary on the outside, yet comes with quite an interesting processor inside. The Valeo CP10 is not powered by Intel or AMD, nor even Transmeta, but instead has one of the first VIA Antaur CPUs we've come across.

This is no ordinary notebook, sporting Intel’s 1.6GHz Centrino processor with a 1MB on-die L2 cache, 400MHz frontside bus and a half gig of DDR. It’s nothing short of impressively fast.

Despite not being the smallest or lightest notebook, this veritable speed demon packs a 3.06GHz desktop Pentium 4 processor and is matched with an ATI Mobility 9000 graphics adaptor and quarter gig of PC2100 DDR RAM. Another notebook to dispose of legacy parallel, PS/2 and serial ports, it boasts a pair of rear mounted USB ports, S-Video output and FireWire connectivity. Also included are 10/100 Ethernet, a 56K modem and single PCMCIA slot for card expansion.

A solid but unremarkable notebook offering a good set of features and excellent warranty.

Looking quite a lot like what I imagined the son of Apple's Titanium and Powerbook lines of notebooks would turn out, the AStone notebook features both the Titanium's solid matte silver magnesium-alloy body with the Powerbook's white limned styling. From the very outset this makes the AStone one visually appealing notebook.

In a world filled with gorgeous Sony, Apple and even Dell laptops, a sober, matte black machine aimed at consumers has to be truly special to turn heads. The IdeaPad Y430 is a well-built Centrino 2 machine that lacks nothing in the way of features, speed or value

Great looks, superb build quality and a world beating software package. It would threaten the A list if it were just a little cheaper.

A super-light laptop with great battery life, but the screen is both its stand-out feature and, for some, its Achilles heel

The ASUS is one tough little cookie. Its cover and palmrest are encased in brushed aluminium lending the unit a reassuring sense of rigidity and roadworthiness. The 15.4" screen is bright, and its default resolution of 1680x1050 makes text sharp but a little small to read unless up close. The unit also comes with a built in TV-tuner, and also sports a TV-antenna output.

This rather small Centrino-powered notebook from Fujitsu has been designed for students and the hip-crowd; those that want something that's capable of work and entertainment, is not too large or heavy to carry, and that can easily balance on a café table between text books and a hot latte.

Wrapped in an attractive silver chassis, this sexy looking notebook is easy on the eye, and features all of the latest gadgets. The left-hand side of the machine features the usual legacy parallel and DB9 monitor out for use with an external monitor, although both are hidden beneath a rubber cover so as not to ruin the smooth clean lines of this housing.

Absolutely jam packed with features, this notebook isn't your run-of-the-mill basic-function productivity laptop. At every turn we found hardware above and beyond the call of duty including a 64MB FX5200 graphics card, sexy widescreen display, 80GB hard disk drive and DVD-RAM/DVD-R/RW slot mounted drive for all your backup and home movie-making needs. A hybrid somewhere between legacy continuation and dismissal, this notebook features three rear-mounted USB 2.0 ports and parallel connectivity.

Its longlife 24-hour battery makes it significantly less portable, but this laptop is classy in every sense of the word.
