why do people always complain if there doesnt seem to be any harm to it?
People fear change :O
Everyone moaned about XP too, which when first released was an unstable, unreliable OS with the security of a sponge door. In other words a complete shadow of its present day self (after 6-7 years of patches and 2.9999999 servicepacks, but is now out of date).
In the trend of XP, 2k and 95(8) vista has many 'teething' problems which will most probably go away given a similar timespan. Personally I cannot use vista as an os in its current state other than B3D testing as it is incompatable both with the way my home network is set up and the way I like to work (or at least last time I checked). At least it *seems* secure (too secure in some ways) time will tell i guess :/
Personally, i wouldnt get too excited and would wait to see how he rest of the world swallows it first :)
