Microsoft officially withdrew support for Windows 98 last year - nearly 10 years after it's release. If corporates demand Win XP support for the next 10 years then Microsoft will be forced to provide it.I agree with John Cormack and think Microsoft are wrong to only provide DX10 support for Vista. PC gaming development is already under threat from consoles and this can only make things worse.Maybe FSXI will only come out for the XBox, the vast majority of people who buy FSX will probably only buzz around some nice scenery in external view anyway.I had a compelling reason to upgrade to XP from 98, stability. XP was a completely different OS to 98 which evolved from the collaboration between Microsoft and IBM (IBM's version became OS/2, MS's became WinNT).I admit I haven't used Vista yet, but I suspect I won't be using it for some time to come as security is not a compelling reason to upgrade as I know how to keep XP secure and I still use the Windows Classic interface anyway!Eventually Vista will replace XP and I will use it eventually but this will probably be at least a year or two.I bought FSX, messed around with it and shelved it until I can make it look as good as the FS9 with addons I currently use. GE PRO 2 on FS9 makes FSX look rather ugly in my opinion.Craig.
