I was surpised the other day when I went to Best Buy and found only one BT mouse... and it was only sold bundled with a BT keyboard.
Noticed they did have a few USB/cordless mice.. small USB dongle that plugs in (like a keychain drive) as the receiver, and the mouse.
Not quite as elegant, but seemingly more available, and while I didn't do extensive research, also cheaper.
Any comparisons between these two types (in general) ? Tradeoffs beyond the obvious use of one USB port? Might one use more/less power/batteries than the other? Would one be more acceptable in an airplane? (or are both bad?)
Thanks,
Mike
