Top 5 slimmest laptops

It may surprise some, but the MacBook Air was not the first superslim laptop to wow consumers. The Sony Vaio X505 was the original supermodel of the notebook world, coming in at a mere 7mm (21mm at its thickest) when most portables at that time were boring bricks.

But it was really Apple's machine that pushed the superslim trend, and since then the market has been waiting for the MacBook Air killer to take on the Cupertino label. With the arrival of the new class of CULV (consumer ultra-low-voltage) Intel processors and AMD Neo chips, we'll see even more lightweight systems in the coming months. For now, here are some of the sleekest models you can find gracing retail shelves.

	1.	Apple MacBook Air (Core 2 Duo processor 1.86GHz, 2GB, 13.3-inch TFT)   CNET Asia rating: 7.9 out of 10 The good: Lightweight and thin; excellent construction; SSD and internal upgrades make the MacBook Air an excellent performer. The bad: Non-removable battery; limited expandability; mini-DisplayPort; thin grey lines visible on screen in some models; over-sensitive trackpad in Windows. The bottom line: If you weren't a fan of the previous MacBook Air, nothing will change your mind here. It does, however, present an excellent user experience. We can only hope the next revision is a little more feature-laden. Thickness: 4 to 19.4mm Review | See full specs | Rate this
	2.	MSI X-Slim X340 (Core 2 Solo U1400 Processor 1.2GHz, 2GB RAM)   First take Despite being over a year old, the Apple MacBook Air is still a huge bull's eye in the ultraslim thin-and-light category to target. The recently launched Dell Adamo just issued a direct challenge, but alas, it comes at a premium price during an economic recession. Fortunately for the budget-conscious, MSI's take on this niche market is a significantly more affordable number with a feature set that beats both the Adamo and MacBook Air hands down. Revealed at CeBIT 2009, the new X-Slim series aims for the fashion crowd with its sleek design. Thickness: 6 to 19.8mm First take | See full specs | Rate this
	3.	Dell Adamo (Core 2 Duo U9300 Processor 1.2GHz, 2GB RAM)   CNET Asia rating: 7.6 out of 10 The good: Sleek, thin design breaks new ground for Dell; good performance for a low-power laptop. The bad: Very expensive; lacks an SD card slot; feels a bit heavier than it looks. The bottom line: Dell's upscale Adamo is a 13-inch laptop for those who value design and finish as much as performance, but its luxury price will limit the potential audience. Thickness: 16.4mm Review | See full specs | Rate this
	4.	Lenovo IdeaPad U110 (Core 2 Duo L7500 Processor 1.6GHz, 2GB RAM)   CNET Asia rating: 8 out of 10 The good: Gorgeous design; lightweight yet solid construction; sharp screen resolution; comfortable keyboard; ships with two batteries. The bad: Lacks a built-in optical drive; glossy screen finish sometimes produces annoying reflections; piano finish on keyboard prone to smudges; fixed configuration can't be customized; no 3G/HSDPA option. The bottom line: The 11.1-inch Lenovo IdeaPad U110 is the most beautiful laptop we've seen in years, and behind those good looks is a well-appointed, fairly priced ultraportable. Despite a few minor nitpicks, we recommend the IdeaPad U110 to those who want a lightweight, eye-catching notebook for frequent travel. Thickness: 18.4 to 22.4mm Review | See full specs | Rate this
	5.	Toshiba Portege R600 (Core 2 Duo ULV SU9400 Processor 1.4GHz, 3GB RAM) Outlook Despite its incredible sleekness, this 12.1-inch business laptop managed to slip in an integrated DVD writer under the hood. Granted this machine is not cheap, nor does it come with massive horsepower. But for the frequent traveler, its impressive battery life and full feature set make this Portege one of the most desirable slim business machines one can have. Thickness: 19.5 to 25.5mm See full specs | Rate this
