It's small because it's a phone. I couldn't imagine holding a laptop up to the side of my head whenever I wanted to annoy every person around me with one-sided details of my mundane life (I don't have a cell phone - - could you tell?)

One of the biggest things that irks me about the potential for tablets is feature creep. Imagine if you had a tablet that had Wifi/Bluetooth connectivity, cell, video/audio playback, GPS, a full 7mp camera w/video recording options, a hardware keyboard, etc, etc, etc. It would only perform several of those tasks well. Feature creep is a dangerous thing that only diminishes the final product for most. I think the greatest example of this that I saw was a cheap $10 mouse from some overseas sweatshop that had a dialpad on top. Your phone handset or headset would plug into the mouse and you'd use the mouse to dial...

That said, I think there *are* some combinations that can be pulled off. The n810 is a good combination of many features but the conflicting form factor considerations between it being a cell phone and it being an internet tablet are too great. How small can you make it before it's a good cell phone and a crappy internet experience & vice versa? The shoddy camera is fine - - I thought cell cameras were a horrid idea until I played with one at the bar one night. You're not taking wedding pics, you're taking spontaneous pics of funny things in the street or your drunken friends. Feature creep, but acceptable as you're not trying to marry a phone with an 10mp SLR camera.
