Medium to high speed Internet through 3G when roaming.
High-speed Internet at Wi-Fi hotspots.

My first decent mobile Internet device: XDA Exec = HTC Universal (2005).

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.


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).

On the Internet since 1987.

Wikipedia: Sometimes I link to Wikipedia. I have written something In defence of Wikipedia. It is often a useful starting point but you cannot trust it. Linking to it is like linking to a Google search. A starting point, not a destination. I automatically highlight in red all links to Wikipedia and Google search and other possibly-unreliable user-generated content.
