I find it pretty easy to upgrade and set aside older desktops, but it’s not so easy for me to put my three-year-old IBM T22 Notebook out to pasture. It runs graphics apps rather poorly, has no Centrino, is relatively heavy and bulky, etc. but I love its ruggedness and the way the keyboard is shiny from long use.
Just today I bought a wireless network card (was using my PHS phone to go on-line while on the move, if you can believe it) to tide me over for some more months (years?) before finally getting a new notebook with Centrino. Really love the X31! Oh, also bought a new battery (miracle mine lasted 3 years).
I dunno, I guess for general on-the-go use it’s still a great machine. Gotta love the fact that it’s running the original installation of Win 2000 Pro. Never had to wipe the drive and reinstall - must be a longevity record for a Windows OS.
