I think 11C is a good aisle seat. Perhaps you will get bumped occasionally during meal service, but you have more space in front of you compare to other non-bulkhead seats. The draw back is that you have to store all your carry-on in the overhead bin (well this applies to all Spacebeds, no storage underneath the seat in front of you). I prefer 11K or 11A. I can store my newspapers and magazines between my seat and the window wall; and I can get in and out from my window seat easily.
