Unfortunately I can't find the v270 in any stores near me. Can anyone comment about the feel compared to the mighty mouse? Any other stuff I should take into consideration? I know that the MM has horizontal scrolling which is kinda cool. The BT MM is really expensive, but it'll match my computer too. BTW, I love how my old MS Intellimouse felt, but the only BT ones I could find don't have that large roundish base that fits into your palm. Any suggestions?
