Got MacAlly's BTMicro wireless bluetooth optical mouse today and am very pleased. Smaller than Apple's, two buttons, scroll wheel, and very responsive. Best yet: it has it's own self-charging cradle. The prospect of frequent battery replacement, and even more so, the nagging "should I or shouldn't I" doubt on replacing the batteries, has held me off from wireless mice up to this point. With this one, just plop it into the no-worry, hassle-free cradle when not in use. Only issue for me is it's rather loud click. Standard disclaimer of no connection to the company.
