I've been gaming with XP pro & home for at least six years & the only thing it was fubar on was certain in particular older games like Home World & Panzer Commander to name two off the top of my head, but that was the game developers fault not the OS.
Anyone who is still clinging to Windows 98 (I know a few too) needs to open their eyes & give XP a fair chance before all that is available is Vista. XP is solid & mine has been crash free & a good performer. I liked 98-SE but it doesn't hold a candle to XP imo It boggles my mind why Microslave is so intent on getting away from XP, it's their best OS since 95 came out.
