Fujitsu is going ultra-portable and uber-portable with its new T4125 (right) and P1610 (left) Tablet PCs. Both LifeBooks feature convertible displays, allowing for usage in both laptop mode and tablet mode, but while the T4215 sports a decent-sized (for a tablet) 12.1-inch display, the P1610 gets by with a mere 8.9-inches of real estate. As for specs, the 1.4-inch thick P1610 gets along fine, with a 1.2GHz Core Solo U1400 processor, WXGA resolution display, 512MB of RAM, 30GB HDD, gigabit Ethernet, 802.11a/b/g WiFi and a fingerprint sensor in the $1,649 base model. Unfortunately, the included 3-cell battery only manages 3.5 hours of battery, but you can spring for a 6-cell battery which promises 7 hours for $45 more. The T4215, which tapers from 1.4 to 1.1-inches thick, bumps the processor game to Core 2 Duo, ranging from 1.66GHz to 2GHz, adds a DVD/CD-RW combo drive and squeezes in a card reader, but the 12.1-inch display runs at a mere XGA resolution. The base configuration, with 512MB of RAM and a 40GB hard drive will run you $1,799. Both laptops look to be available now.
