Apple iPad's 3FF SIM Card Slot (not SGP Friendly, yet)
The SIM -- that tiny card that holds your contact info and account information that you find in your GSM handset -- is a 15 x 25mm plastic card whereas the new Micro SIM (also known as a 3FF SIM) is a diminutive 12 x 15mm, about 52% smaller. Needless to say, it's not physically compatible with your current phone. This card was developed by the ETSI (European Telecommunications Standards Institute) to offer things like more storage space on-chip for provider applications, increased control and security functions -- over what, we don't know -- and the new smaller form factor allows it to fit in tiny devices. Frankly, we wouldn't call the iPad "tiny" and we have absolutely no clue what justification Apple had to switch to it other than a desire to be different -- this is the company that pioneered Mini DisplayPort, after all -- but the long and the short of it is that you're going to have a hard time finding a carrier offering Micro SIMs in the short term since the GSMA doesn't appear to be actively spearheading a mass conversion.
All of the built-in apps on iPad were designed from the ground up to take advantage of the large, Multi-Touch screen. And they’ll work in any orientation. So you can do things with these apps you can’t do on any other device.
