Mobile user.

Extremely-mobile roving user (compare with semi-mobile user of wireless LAN).

Handoff problems.

WAP
WML
Limitations of WAP
Google translates HTML to WML on the fly, so WAP users can view the Web, sort of.
My links for WAP phone show how to view HTML pages, and how to make a phone number clickable.

Web access on a WAP phone will look something like this.

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.

Tablet
iOS (closed source, ultimately based on Unix)
- iPad (the pioneer tablet)
- App Store (Apple iOS apps)
Android OS (open source, based on Linux)
- Samsung Galaxy Tab (my first tablet)
- Google Nexus 7 (my current tablet)
- Google Play (Android apps)

My first tablet: Samsung Galaxy Tab (2010).
