Everybody will talk about it and everybody will know that Microsoft is limiting XP users to push them at buying their new Windows 7 OS.
They did the same with directx10 and vista.
I'm sure it's pretty easy for them to devellop a patch for XP to support those IMPORTANT FEATURES like double buffering, next directwrite API (text) correcting shitty WPF small fonts bug, directx 10.1 and direct2D etc..
I'm sure windows 7 is gonna be quite popular no need to cripple users. It will actually give them a bad name and they should instead really work in the direction of being friendly and sincere to all windows users not just new buyers.
I hated vista but i wanted directx10 , i still decided to stick to XP because it's like a 300hours work to just reinstall all my programs, addins, vsts ect, reconfiguration etc..
I will buy windows 7 no worries and run it in dual boot but still i need my XP to AT LEAST be FIX for the WPF font bug, visual studio 2010,tearing fix, support for Directwrite and also some hardware acceleration would be great.
What will i say to every company that use XP, if i want to sell them a WPF application. Sorry you gonna have to change everything upgrade everywhere to windows 7 if you want to be able to see the text clearly in my application that i spent 9 months develloping.
Clearly, you can put nice words here and there but if WPF application work badly on XP your gonna loose a lot of support from everywhere. Think about it, your on a nice road now with windows 7 no need to spit against the wind.
Everywhere you promote the new WPF 4 and new WPF interface for visual studio in the 2010 release but if you don't fix all those XP WPF bugs for the final release then your risking a lot believe me. You might be able to control review sites a little but you cannot controls forums review.
(Like if every company will be able to pay upgrade cost to both visual studio 2010 + Windows 7 for every devellopment computer at the same time)
Believe me all XP devellopers will fight until they have what they want and the only way they can fight is on forums like this one.
You don't want all those devellopers to bloat all your forums with post like this one
