I'm trying to work out what a science fiction webcomic has to do with e-mail?*
Unless you're secretly Howard Tayler, in which case I claim my five quid. Or something. ... Though as far as I know, Howard lives in the States, not SA.
Seriously, though, I don't think anybody uses their smartphone to its full potential. A wrench, yeah, it pretty much has one job, pretty easy to meet that potential. But a smartphone? "Swiss Army Knife" doesn't even begin to scratch the surface of what it's capable of, even if you only include the apps currently available, not the potential of apps yet to be written, or that could be but never will be.
Does it do what you need? Good enough. Is it excessive? Next time consider a dumber phone. But don't try to make yourself stretch to fit what the phone can do. A tool is supposed to be there to help YOU, not the other way 'round.
*I'm not actually trying to twit you on this, but naming one of my favorite webcomics caught my attention. :) Like SF webcomics? Have you seen Quantum Vibe? For a more Steampunky feel, try Girl Genius.
