I am sick of downloads from Windows messing up the layout of my current laptop. I intend to keep this laptop off-line and use it for all my Photoshop and photo filing work and buy another laptop that I'll use for the internet. Chromebooks look to be exactly what I want, with a USB port, but I am wondering if I can use a Logitec trackerball mouse with a chromebook? Has anybody tried this, or even a normal mouse? I don't like the built-in pads on laptops.
