I've got one and I love it. I use my iPad on the road all the time and it is great for being on a plane and still busting out emails and getting the writing done I need to get done. It is cheaper to connect a mobile device like an iPad to airplane wifi, so I just use this instead of my laptop. I also take over my PC at home or in my office all the time, and having a keyboard makes it easier for me to use some of the things I need to access.
This is where I was looking to buy mine. I wound up getting it on ebay a couple months ago for a little more than that, but that was also when the price was higher. Now that it is down to 65 bucks you really can't beat it. When you factor the cost of a good case and a bluetooth keyboard, this is as low cost as you can get. I bought two more for gifts and I know they will be greatly appreciated and useful.
