I went ahead and ordered the Adesso remote from buy.com for $20 shipped and received it in the mail yesterday. It really is a great remote. It is smaller than I thought it was going to be but it's a good size and fits comfortably in my hand. The mouse pad feature is a great added bonus that sets it apart from all the other MCE remotes. The mouse feature did not function the way I thought it was going to and at first I thought it was broke. From the pictures I thought that you were just supposed to glide your finger on the pad like you would with a laptop trackpad, and it wasn't responding. You actually have to press down on the round button to get the mouse to move. One you hold it down the mouse begins to move slowly in the direction it is pressed, and then it will move faster after a few seconds. It takes a minute to get used to but it is definitely a helpful feature. Don't plan on using Word with it, but for light web browsing and opening and closing windows it does the job and allows me to keep the mouse in the entertainment console.
The IR sensor is also great. I can point it in any direction in the room and it still works, unlike my cable box remote where I have to point it directly at the box or it won't work. Highly recommended!
At this point I'm thinking about just dumping cable altogether and picking up some tuner cards for my htpc. Between OTA shows and Blu-ray there isn't much time left in the day for anything else anyways.
