Don't blame Microsoft, that's market competition. Nokia's been digging their own grave since about 2008.

Okay, now Windows may be insecure from malware, due to it's wide use, and Vista may not have been all that great (wasn't as bad as they claimed, ha, don't put a modern OS on an old PC.), but you can't call Windows any more buggy than any other OS. The most modern over-buggy OS is Leopard. Snow Leopard fixed that though.
