The iPhone was a revolution. First proper mobile phone Internet. First proper multi touch.

For a time, multi-touch smartphones dominated mobile Internet usage. But then tablets arrived.




Tablets

Bigger device. Much easier to use Internet, but won't fit in small pocket.
There is probably room for every size.
I prefer 7 inch tablet to either 11 inch tablet or 4 inch phone. You may differ.



My first tablet: Samsung Galaxy Tab (2010).
