Hello, you are right. Windows 7 is by far as fast as xp and will outbeat vista anyday. Microsoft is now calling vista a trail-n-error but no one is perfect.
After this year, xp will come to a stop as microsoft is in the works on Windows 8 as we speak but wont come out for a few years to come.
Acer does support Windows 7 drivers. Here is the link to get them. As of now, Windows 7 drivers itself is not listed, however you just need to use the ones from the Windows Vista Drivers and install them.

You can also use the Microsoft Windows Update as it should give you the missing drivers as well.
BEST OF LUCK!GOD BLESS!
