"Non-security critical fixes will be available to those punters who signed up to Microsoft’s Extended Hotfix Support program 90 days before mainstream support was killed off."
Non-security.
Notice that they're effectively saying "8 years wasn't enough to close all the security holes".
Whatever makes them think that I'll be upgrading to any of their new OSs when after many long years of development and 8 years of actual use they still can't close them?
Windows 7 isn't going to be any better. You can tell yourself whatever you like.
...and the poster who asked if Win7 is likely to run in 512Mb of memory. I've seen unix systems that came on floppy disks and used less than 512Kb (not Mb, Kb) of memory, by the time I had WIMP going, it was still less than 512Mb BY A LONG WAY! What does an operating system need more than 512Mb of memory for? Can anyone answer that? The Amiga had a reasonable OS going in about 100k of memory (usually much less) same with the Archimedes etc
If I was MS, I would concentrate on taking XP and
a) making the damn thing a lot more secure
b) removing bloat.
Strangely, I suspect that merely doing b) would help towards a)...
I suspect that once XP support and security updates have gone the way of the dinosaur then many people will be switching to a friendly flavour of Linux...
