HP TC1100 and the iPad

I've had a TC1100 for a while now. I just decided to get a new battery since the old one wouldn't hold any charge.   So as I sit here using it with Win7 it occurs to we that this is pretty much the exact same size as the iPad.   Sure its a little thicker but the screen is the same. Even down to the bezel.   So whats different? For one thing this requires a pen.   This is a good thing and bad.   The handwriting recognition isn't too bad but I do have to fix things sometimes.   Plus everything requires the pen. Sometimes it would be nice to just flick something with my finger.   So, despite being a really cool form factor I can see how the iPad would be alot easier to use.The lack of camera really annoys me but maybe I can live without that after all. maybe...
