Might just suit my wife...
...who really doesn't get on with touchscreen keyboards, wants a phone that doesn't need charging every evening, but could do with a bit of internet connectivity (maps, email) while out-and-about and can't justify shelling out every month for a data-only SIM for a tablet.
Pair this phone with a cheap Android tablet and I think she'd almost have the best of both worlds; a phone to use as a phone, with a real keypad for texting, and then a tablet (tethered to the phone - though I think I would prefer Bluetooth tethering to WiFi - doesn't say if this is possible) for internet when needed. She currently has a Samsung XCover 550 which does all of this except for the tethering, which is only available through USB. Works fine for a laptop, not so much for a tablet.
Just so long as I can delete Facebook and Twitter. Hmmm.
Of course, all this ignores the fact that five or six years ago there was a plethora of phones that would have fitted this bill (keypad, battery, useful internet) and now there are next to none. If someone would bring out an updated Sony k800 or Nokia 6220 classic, I'd be happy too - I just like the form-factor, particularly the shutter on the back for the camera.
