What a dilemna. Im torn between the Logitech MX900 and the MX1000. See, the problem is my Apple Bluetooth Mouse is kind of sluggish and imprecise, and only one-button'ed, compared to usb mice at school. So when Im using Adobe Photoshop or illustrator at home, I feel left out. Ive been on other threads and some people swear by the MX900, some people say it sucks and if im gonna go wireless, its gotta be the MX1000. I'd really like to hear from anyone that has had the privilage of trying both.
