As a couple of posters know already, I test rode a bent today:
Well, not exactly rode it. More like I was pushed. I found it impossible to remain upright on the bike. Between my sense of balance, slightly off to begin with, and the super-sensitive steering of a bent, I had to be held from behind during the 20 minutes or so I test 'rode' it. Every time I started off I veered sharply to the left- I have the same problems on uprights, but I can correct for it in a second or so. I don't know if it's bents in general I'll have a problem with, or just this one, but for now a recumbent is NOT something I am pursuing.
Tom Stormcrowe may be right that a trike is what I should be riding.
