ok I've used 7 a bit more, and I can't help but feel really disappointed.
The first issue is I've noticed is no difference in performance, I'm not sure if it's people comparing a seasoned vista/xp install to a fresh 7 one, but personally I've found it to be exactly the same as Vista.
Then all the major changes seem to be mainly aesthetic, which they can easily implement into Vista, such as the new version of Paint, Wordpad etc.
I'm sure there are numerous under the hood changes which may be crucial (I'm not knowledgeable in this field whatsoever though), but it looks to me nothing has really changed at all - other than the new less annoying UAC. Although there's already proof that the newer UAC doesn't work as well as Vista's anyway, I'm inclined to agree with people calling it a Vista update because, well, frankly that's what it really looks like.
I'm actually expecting for someone to tear me a new one and explain how it's so much better
. But like the old saying goes, he who asks a question is a fool for 5 minutes, he who doesn't is a fool forever
