as someone who had a peg tube in for about a year following a hospitalization: It's both convenient and inconvenient. Yes, you can blast through a 'meal' quickly, with no cooking, but you still need some prep and cleanup of the special equipment. Also It can hurt like a bastard if it gets caught on something. And god forbid the clamp/valve come open when you're tossing and turning in bed. That was not fun to clean up.
