Although I wasn't entirely blown away by my brief twenty-minutes-or-so experience with an Ipad in Glasgow's Apple Store, various reviews and commentary such as this got me thinking that sometime somebody's going to have the clever idea that what we really need is a kind of missing link, halfway between the Ipad and an actual laptop: essentially, a laptop with a screen you can lift off a mount and use as a touchpad if you so choose. That way you've got a machine you can browse on while lying half off the couch, then take through to your home office, click it together with the keyboard (or into a frame containing the keyboard) and use it exactly like a regular laptop.
Then I saw this and realized that the world had once again figured this out long before me. Unfortunately, they all run Windows. Yech.
Which brings me to my next prediction: someone's going to come up with a hard-case for the Ipad and its bluetooth keyboard that essentially simulates a laptop, while allowing it to retain the convenience of a standalone touchpad. Then we're really talking.
Edit: Oh. Right. Duh. According to Blarkon in the comments, it's already here. And it is rather pretty.
