Speed doesn't always win the race


IBM's latest ThinkPad is the fastest notebook we've seen yet, at least for application performance. The rest of the solid but unremarkable system mixes robust security features and endless expansion options with staid design. Blazing speed...

Back to Thinkpad


I purchased this IBM T23 2647 last year used, to replace my dying Armada M700. After previously owning a Thinkpad 600E before the Armada, I decided to go back to IBM. Specifications: - Processor: Intel Pentium III-M 1.13 GHz - Installed ...

A pro's pro laptop


This is a computer for people who like computers. It's now over 5 years old. It can't run Vista, it can't display HD video -- but what it does do it does damn well. I'm in the laptop repair industry and have sold and serviced dozens of different ...

IBM ThinkPad T23 (8MU) Refurbished


I purchased the IBM T23 ThinkPad (8MU) directly from IBM's Certified Used Equipment website. After assessing my needs, shopping around for various laptops, and reading earlier epinions about the T23, I decided to go ahead and purchase one. It has ...

Consumer review by: alano_g (



Even in early 2002, IBM was ahead of the game with the ThinkPad T23. A Titanium outer cover protects the display, and a handy keyboard light is available at the top inner, left edge of the cover. I've had 4 laptops in the past 6 years, and there's...

Great keyboard, fast, decent HD size, adequate memory, OK speakers, comfortable size and weight.

Mediocre battery life, higher screen resolution option would be welcome.
