When people think of tablet computing, they think of larger 10-inch or greater displays that are in either the traditional slate form factor or comes in a convertible, laptop-like exterior, but UMPC Portal reminds us that tablets come in many different sizes and form factors, from large screened tablets to small screened smartphones and mobile internet devices that has a touchscreen, can handle finger or pen input, and perform some handwriting recognition if you need it to.

Are you using a tablet? If you’re using an iPhone or a smartphone, like the HTC Pure (3.2-inch display) running Windows Mobile as its operating system, you’re using a tablet. Modern day smartphones and PDAs, while they don’t run a full blown operating system like Mac OS X or Windows, still do perform many of the tablet tasks. It’d be interesting to see the future of tablet computing as smartphones gain more power.
