Just performed a clean install of WinXP and SP2 on my M275. I'm pleased to inform you all that I had no issues with it. Everything is working just fine[thumbsup].
The new TIP is outstanding. The final release of SP2 has come a long way from SP2RC1. My Broadcom wireless card and all peripherals are working just fine.
I still recommend backing up all of your important data prior to updating.
