I guess it'll work just fine for some people. My cousin doesn't browse on her phone but only uses whatsapp and sometimes texts. The front-qwerty takes lots of space, but it doesn't matter if you don't need a lot of screen for webpages and such.

I think the blue version will also look much better than the banana, ehm, yellow phone. A nephew had a yellow Nokia Lumia, everyone's first reaction was really "nice banana" :P
