Tablet PCs

Fujitsu LifeBook P1620
The Fujitsu LifeBook P1620 makes a few notable improvements on its predecessor, but a new breed of cheaper mini-laptops are on the horizon, making this ideal only for heavy tablet users, who may prefer a full-size tablet.

Axiotron ModBook with built-in WAAS-enabled GPS (Core 2 Duo 2.2GHz, 2GB RAM, 160GB HDD)
We're impressed with the engineering behind Axiotron's rebuilt, tabletized MacBook, but the target audience is likely very small, especially since Windows-based convertible tablets do so much more.
Specs: Intel Core 2 Duo (2.2 GHz), 2 GB DDR II SDRAM

Toshiba Portege M700-S7002
But for its disappointing battery life, the Toshiba Portege M700 is an excellent hybrid of power laptop and well-designed tablet.
Specs: EPEAT Gold, Intel Core 2 Duo (2.2 GHz), 2 GB DDR II SDRAM, Mobile Intel GM965 Express

HP Pavilion tx2000z
HP's Pavilion tx2000 combines a convertible tablet design with an entertainment-focused laptop to create an interesting hybrid, thanks to an improved tablet screen and mini remote control.
Specs: AMD Turion 64 X2 mobile technology (2.1 GHz), 2 GB DDR II SDRAM, 4.4 lbs, 12.1 in TFT active matrix, Microsoft Windows Vista, Microsoft Windows Vista Home Premium

Fujitsu LifeBook U810
Ambitious but flawed, the Fujitsu LifeBook U810 has more of a traditional laptop design than other UMPCs, but the otherwise excellent keyboard is marred by the loss of several important keys.
Specs: EPEAT Silver, Intel A110 (800 MHz), 1 GB DDR II SDRAM, 1.6 lbs, 5.6 in TFT active matrix, Microsoft Windows Vista, Microsoft Windows Vista Home Premium

HP Compaq 2710p (Core 2 Duo 1.2GHz, 2GB RAM, 100GB HDD, Vista Business)
HP's attractive Compaq 2710p convertible tablet suffers from one fatal flaw, choosing a ThinkPad-style pointing stick over a touch pad, effectively ruling it out for a large number of potential users.
Specs: EPA Energy Star, Intel Core 2 Duo (1.2 GHz), 2 GB DDR II SDRAM, 3.7 lbs, 12.1 in TFT active matrix, Microsoft Windows Vista, Microsoft Windows Vista Business

Fujitsu LifeBook T4220 (Core 2 Duo 2GHz, 1GB RAM, 80GB HDD, Windows XP Tablet Edition)
For business users who don't want to compromise, the Fujitsu LifeBook T4220 is both a full-fledged laptop and a handwriting-friendly tablet--though we recommend tweaking the base configuration.
Specs: EPA Energy Star, EPEAT Silver, Intel Core 2 Duo (2 GHz), 1 GB DDR II SDRAM, Mobile Intel GM965 Express

Gateway E-155C
A no-nonsense, 12-inch convertible tablet, the Gateway E-155C fits an optical drive into its tiny frame, but it skimps on amenities and battery life.
Specs: Intel Core 2 Duo (1.06 GHz), 1 GB DDR II SDRAM

Lenovo ThinkPad X60 Tablet (Windows Vista)
The lightweight Lenovo ThinkPad X60 Tablet now runs Windows Vista--and remains one of the best convertible tablets on the market.
Specs: EPA Energy Star, Intel Core Duo (1.66 GHz), 1 GB DDR II SDRAM, Mobile Intel 945GM Express

Asus R2H Ultramobile PC
The Asus R2H is too big to be truly ultramobile, but its relatively large screen and decent battery make it good for on-the-go Web surfing and media playing, even if the onscreen keyboard is a chore to use.
Specs: Intel Celeron M (900 MHz), 768 MB DDR II SDRAM, Intel 910GML Express
