I love XP and I miss like crazy my laptop that was maded in the XP era.
It lasted 4 years. Had there not been a problem with a video card, it would have lasted much longer. For a couple months, I had a heavy bulky monitor hooked to the laptop. It became so cumbersome that I relented and got a laptop with Vista on it.
I had it for under 2 years and it started slowing down, battery problem, audio driver problems...and so many more things.
I still use it as a backup, and for minor projects that require PC language, such as an antiquated Mp3 player and I still dump photos on the PC and then from the portable hard drive dump it to Mac. Sounds like a pain, but then I have an archive in three places. The PC, the portable drive and then on the Mac.
I still use the MS OFFICE and Firefox...but I know I should learn the Mac language a little better.
