The Bottom Line If money is no object for you, the Toshiba Portege R400 is an eye-catching, Windows Vista conversation piece, but the rest of us will want more performance from a system this expensive. But for its disappointing battery life, the Toshiba Portege M700 is an excellent hybrid of power laptop and well-designed tablet. The lightweight Lenovo ThinkPad X60 Tablet now runs Windows Vista--and remains one of the best convertible tablets on the market. With the LifeBook T1010, Fujitsu adds tablet functionality to an otherwise typical 13.3-inch laptop. It's a good choice for students and executives who prefer to take handwritten notes on the run. Though inexpensive, the Portege M400 convertible tablet's middle-of-the-road performance and battery life may not be enough for the demanding business user. For basic tasks, however, it's a decent bargain.
