The flex thing is awkward but understandable. Although I do plan to walk around the house while non-chalantly having full-screen HD video-calls with people like its an every-day thing whenever my friends come over. The 17 would be most hilarious for that...

If you don't care too much for portability, the 17" sure is a great machine. The speakers sound really good (for laptop speakers) btw. If you're traveling a lot (plane, buses, subway etc.), I'd recommend the 15", though.
