95 and 98 are defunct but the 9x interface was a big step up from 3.11,
xp is nothing special
vista has integrated security but is plagued by peni5 users who think they are pc experts but cant find drivers etc
I use vista and have no complaints
everything works fine
by gaming is fine even if because i have always had newish graphics cards and high amounts of memory
as long as you have a good spec pc youll be fine with vista, im perfectly happy clicking allow when i open programs as it ensures i dont have spyware and other malicious crap self opening which happens loads with xp
Anyone who says vista is full of bugs is the computer equivalent of a sun newspaper reader or pub football expert whos never seen a live game
Anyone who says its not compatible with programs doesnt know how to use compatibility mode, exactly the same as you have to for a 95/98 game
anyone who says its not compatible with hardware...Microsoft dont write drivers, hardware manufacturers do, it their fault if they havnt written one but theyre not interested in writing drivers when they can sell you a new piece of gear
bear one more thing in mind, people with bad comments on here are probably using pirated software, the best OS is the legal one =)
