Mobile phone sizes

I remember the first mobile telephones, they were boxes about the size of a video recorder with a great big aerial and a telephone handset.  The trend was to miniaturize things in those days, so mobile phones got smaller and smaller, until... well frankly it got silly, I had a nokia 8210, the thing was tiny, and I have big-ish fingers, fiddly to use or text wasn't the half of it, bloody nearly impossible was a better description..

Now we're going the other way, phones are getting bigger again, while this makes it easier for those with big hands it also creates another problem.  You see for a mobile phone to be useful it has to be mobile (the clues in the name really) now the mini tablet/phone are so big some people no longer carry them around all the time. 
They won't go in a shirt or trouser pocket, they bulge a small handbag (a heinous crime I'm led to believe) So unless the person has a laptop bag or something similar they can be tricky to lug around.

So where do we go from here.  Well I suspect beofre long we'll be back to the big box with an aerial on a backpack (like the old army radios)  Oh the camera will be great, and the picture on the 15 inch screen will be stunning, but a lot of people will end up with bad backs.... untill some clever bugger comes up with a smaller pocket size phone.....  Oh wait......
