Actually does not look that appealing at all. I am buying a tablet because I want a tablet, not a netbook. I want a couch surfing device that I can hold comfortably and control with a few hand/finger swipes. It is most certainly not a device I want to do much work on. For that I have my desktop with a comfortable keyboard, fast processor (lightning fast compared to a tablet) and a full OS. If I absolutely must do some work on the couch, I have a Macbook Air which, again has a better keyboard, faster processor (much faster than even one in a real netbook), and a full OS.
As such, I am not looking for a tablet to try and replace any of my computers, especially seeing as it really can't even if I wanted it to. As a result an attachable keyboard is an unnecessary accessory that makes this device more clunky when attached, taking away from the simplicity and comfort of a tablet-type device.
As far as the Android versus iOS argument, I actually have mixed feelings. I have Galaxy S phone, and I certainly love the flexibility and openness of the android system. Just being able to copy any common movie format to the phone like I would to a USB flash drive and be able to play them is absolutely great. Having to reformat most movie formats and then use iTunes before being able to view them on iPod/iPhone/iPad feels retarded in comparison. On the other hand, the smooth operation of the idevices is really appealing and even the latest iterations of Android feel clunky in comparison.
