Dell Inspiron Mini 9 Netbook on Vodafone

These days its possible to use phone (3G and Smartphones) to make GSM calls, GPS and Internet surf.
Are there netbook PC computers that can do the same thing. i.e. you put the 3G sim card in it and it can be your GSM phone, GPS and surf unit all in one. Like a smart phone (only bigger)
How difficult is it to change the situation around?
I am looking at GSM phones lines now, not Skype. net2Phone/ CallServe etc

I've been using mine for a couple of months now, I get a little over 3 hours use with the standard battery and reasonable use of the 3g connection. I also have the extended battery which I haven't managed to run out yet (well over five hours and I'd guess about seven is the limit). I really like it, I travel a lot and the small size and small mains adapter are perfect for my needs.

I've upgraded the memory to 2 gig ram which really helped and the SSD to 32 gig which has made it much more usable for a full blown MS Office 2007 suite including groove which I need when I'm travelling.

The HSDPA adapter also has a built in GPS receiver that isn't mentioned in any of the documentation. This is rather odd as I'd have thought this was a real selling point.

I need something to use purely for internet browsing (basically facebook and email), storing music and storing photos. These mini notebooks appear to be ideal. Are they?!

I was looking at the Dell version because I have used Dell before and been satisfied with the product. Any advice would be appreciated.

It likes that ASUS Eee PC, enough for internet browsing (basically facebook and email), storing music and storing photos.
