Most likely old news for some, well I just found out about it couple days ago.
. One thing i missed is Vista's sidebar I gotta have all the gadgets and radio stations while im surfing have tried a few homemade sidebars for xp and found them all to be half finish or just a virus waiting to happen.
Google sidebar can be trusted works well and plenty of gadgets to choose, although i couldn't find any radio stations gadgets yet.
