As a home computer user of windows XP with full install licenses, its beyond me why I should rush out to shower microsoft with my money every time they diddly darn well feel like coming up with a new OS. Especially when every new microsoft OS becomes ever more bloated than its predecesor and offers me nothing in terms of must have new features.
The only feature I now like about windows 7 is better security, but I have already learned how to lock down XP computers with third party freeware and tweaks which has a knock on wood track record of keeping my XP computer and my wife's XP computers free of malware ever since win XP came out.
Sadly I have not had as much luck with my computer hardware which is why a full package is almost required. To retain the ability to transfer the license from a dead computer to a newer one. And if I buy a win 7 license now times three computers, oh goodie, in another two years microsoft will want me to buy their next upgrade. Its a very good way for microsoft to future proof their profits at my expense.
Sorry Bill Gates, I still don't have my money's worth from Win XP yet. And I hope someone will honestly or dishonestly take windows XP, and modernize it, and that I would pay for. Sadly Linux will not run windows software, but when and if some Linux like OS becomes available that does run windows software, microsoft will instantly go to the top of my never buy list.
