i bought a bluetooth mouse at best buy this weekend. i like it. my laptop already has bluetooth so i don't need to use the extra dongle included. it's so easy to use too, light, and power-efficient (i assume). i just have to click to get it to wake up, in both windows and linux. my older logitech mouse sucked somewhat because they need the big dongle, it didn't have an explicit on-off switch, and it broke when i dropped it
all i need now is bluetooth headphones and i'm all set
