It ain't the first company to do it, but Logitech's new iPhone app is certainly one of the easiest to get into. Oh, and did we mention that it's completely free to download? Available now in the App Store, Touch Mouse transforms your handset into a wireless trackpad or keyboard, and thanks to its reliance on vanilla WiFi signals, you won't need any proprietary equipment to get it up and running. It's fully compatible with both Mac and PC platforms, and it's obviously a pretty fantastic way to control your HTPC without dragging a full-fledged keyboard / mouse into the living room.
