of course its gonna be big. u cant be suprised by that. its a major part of an OS, with like a gazillion bug fixes incorporated in it(remember those almost daily updates in september-november??) and an updated version of Windows Update (i mightget to beta test it
) and IE improvements. this is gonna be big. and its got an improved Firewall, which is turned on by default (ur computer wont let you log in until its configured), and might not be so simple to turn off (it MUST be possible tho). so expect something big.
