I'd rather have a Nokia 8110. Now there is a more ergonomic phone.
Ah, the bananaphone. A classic.
I have a "phablet", Note 2, and find it a good size for all the tablet-like tasks I want it for. Great for ebooks, the odd website when needed, taking notes, playing games
I don't have a proper wired headset, but I do use headphones with it when calling sometimes, the phones mic is sensitive enough to keep it a decent distance away. Audio quality is really good though some nice IEMs.
It has a great stylus and handwriting recognition, too, so you don't need to use the touchscreen keyboard, but I do when I need to use it one handed.
I used to pooh pooh all the radiation studies since the radiation levels from a mobile phone are far from ionising level, but recently have started to be interested, since I read a paper about cell division. Apparently, during a crucial stage (formation of the mitotic spindle?), the process relies on polarised dipoles and electric charges to function properly. If radiation of a crucial frequency (they found effects in the 100 to 300kHz range) and enough intensity is introduced it interferes with the process.... Catastrophic for the cell in question. They are investigating it as a method of treating cancer, since only currently replicating cells are affected and the radiation is absorbed fairly rapidly by surrounding tissue and thus is relatively local.
That said, mobile carrier frequencies are in the hundreds of MHz range, so I don't think there's much risk there, but some of the other components of the device may well emit radiation in the 100 to 300kHz range, although probably in fairly low intensity.
Of course, the cells affected usually just die, instead of completing replication with damage, so the chances of this actually causing cancer is minimal and even if it does, there's a greater chance of it killing the resulting cancerous cells anyway, but it does point to the fact that radiation can affect cells in ways we may not yet be aware of, so it may pay off to be cautious about this. Especially for babies and young kids who have a rapid rate of cell division.
