One of my favorite new products for business travelers is the ultra-portable MoGo Mouse, a wireless Bluetooth device that folds up to fit (and recharge) in a spare PC card slot in your laptop. Problem was, it used to be a bit on the pricey side: $70. Well Buy.com is currently having a sale on the MoGos. For $30 (and free shipping!) you can make your favorite business traveler's day, even if said traveler is you.
