I've switched over to a Microsoft Surface RT from an iPad + Sony laptop.

For tablet duties like apps and web browsing I still think the iPad was a bit better/smoother, but the Surface does enough "real computer" duties that it lets me leave the laptop at home when I travel. I used to have to lug the laptop for presentations, editing powerpoint/word/excel documents and so forth, and I'd use the iPad for "fun". The Surface is a bit of a jack of all trades, master of none, but it's awesome for travelling. The touch keyboard is pretty cool.

On my last trip I ran out of space on my digital camera, but I could plug the camera into the USB port on my Surface, upload the files to Flickr, and clear off the camera to make more space. And after checking in with the airline, I could plug it into the printer at the hotel and print off my boarding pass. Try that with an iPad or Galaxy tablet!

Typical Microsoft though, it does feel a bit like a beta product. I think when they get this thing right it's going to really catch on.
