I've given up trying to find a nice Bluetooth mouse for desktop use, and none of the trackballs available nowdays are any good. So I'm leaning towards the Logitech MX Revolution cause I've head good things about it. I just have to get over the ugly looks Anyhow, I'm also going to buy a Cordless RumblePad II since I'd like to play the old emulated video games with some style (and perhaps some new ones). Thing is. I'm not happy about the dongles. And the RumlePad uses a really ugly solution with a cable and a box. So I'm wondering, will I be able to use both devices with the same receiver? They are both using the 2.4GHz frequency so I was thinking that it might be possible. But then again, you never know. Thanks!
