What's the point? Surface Pro has few to none of the advantages of either device category it's competing in. It's very expensive for a laptop yet the cheaper laptops are better in many areas (battery life, performance, peripheral I/O, keyboard/mouse, etc.). It's also extremely expensive for a tablet yet tablets are also better in many areas (battery life, size, screen, pen input, apps, etc.).
This is cool no doubt. But not very practical. It's trying to be everything when it's good at nothing. If I had ~$1000 extra cash lying around, I might try this. But from the reviews I've read, some praising it and others not, it doesn't seem to stack up well at all compared to any competing device on either PC or tablet side.
Nevertheless, I might be wrong (I really looked forward to Surface Pro actually), so if the OP could continue posting about his experiences, I'm very interested in reading about it and I might change my mind.
