i have a 17 inch umbp and I carry mines around everyday to school. not a problem at all.
what i use to keep it safe is the moshi codex, works very well. I also have the stm convertible bag and the mbp with the codex fits perfectly in it (though i wish there were more pockets for other things).
if I were to reconsider things to get, I think a backpack that fits well with plenty of pockets that doesnt look too bulky, or a messenger bag would be a good choice. Plus maybe an incase sleeve, or booq sleeve. the moshi might be a little too much (but i do like it a lot, feels really safe) or if you dont need to carry much other things, a waterfield sleeve with the flap and piggyback would be nice, I still want one of those
