IBM ThinkPad T42 with Biometric Security Review (pics, specs)

IBM ThinkPad T42 Review (pics, specs)


The IBM ThinkPad T42 with Flexview is a damnably frustrating machine. It s not that it s a bad computer. Quite the opposite, it s easily one of the best thin-and-light business laptops on the market.

IBM's new ThinkPad T42, is a healthy 5.4lb boy!


Okay, we don't really know if it's a boy-it can be really hard to sex these things sometimes-but what we do know that is that the ThinkPad T42 has got WiFi and Bluetooth, a relatively lackluster 15.1-inch screen, up to 2GB RAM, the trademark IBM...

ThinkPad T42 Notebook


IBM creates another fast, well-equipped business notebook.

IBM's latest slim corporate notebook has the same great keyboard and expandability as its predecessor. The ThinkPad T42, a peppy performer, offers a strong value for $2299. Business application software is not included in the price

IBM ThinkPad T42 2378-EXU


Business users take note: IBM has added a 15-inch display to its flagship ThinkPad T42 line. For an additional $50, you can get even more of the T42 you already know and love, which includes 15 percent more screen space—if you don't mind a bulkier...

Gorgeous 15-inch display. Same great fit and finish, manageability, and protection of other ThinkPads

Below-average wireless throughput. Marginally heavier, one-quarter bulkier than the 14.1-inch T42

IBM ThinkPad T42


The IBM ThinkPad family has always been highly regarded for its reliability and dependability, and their keyboard feel is unmatched among its peers. ThinkPads have also had the rap of being pricey, so we were surprised to see that... click here for

Sharp screen; great ThinkPad keyboard; one-button access to self-serve help and diagnostics

Getting a wireless connection profile to work can be tricky

We couldn't have guessed the ThinkPad T42 would be the value leader in the crop of new Dothan-based portables. It's well-priced for a system of this caliber, but note that others deliver better performance and more features (albeit for more money).

The T42 is the Place to Start


When I set out to research a new laptop, I quickly had the reaction that many in my position probably do: nausea. There are so many laptop brands, so many proprietary technologies, so many marketing ploys - it's a thicket. The chain stores (Best Buy...

Powerful, Relatively Light, Good Battery Life, Good Value, Amazing Engineering

No dedicated 'Windows' shortcut key. I hate that!

Laptops are portable, they're stylish, and let's face it: the opposite sex will think you more sophisticated when you're suavely tapping out your latest blog entry at the coffee shop. Okay, that's probably not true, but they are fun to have for both...
