Until about five months ago, I had been using the legendary Motorola F3 ( http://en.wikipedia.org/wiki/Motorola_FONE_F3 ) for something like two years. Amazing phone, just the absolute basics: even SMS messaging was somewhat difficult. Due to it's e-ink display the battery lasts almost a week. It was a great conversation piece too.
Let us face it. Anywhere I am (home or office) I have at least 4 different ways to connect to the web and waste my time over there [;-)].
Actually, it was for this reason that I moved on to a blackberry, I was constantly spending time checking my email. Naturally, by the time you open your browser you go on to check other things etc etc. Now I write (personal) emails almost exclusively from my blackberry and it has made me much more productive.
I would have gotten and Android if there had been a model with physical keyboard which I could have gotten, but alas it was not the case.
