I've played with micro in different contexts, and I was not impressed. I would not use it. It goes from fast to VERY slow over different periods of time.
I did compare small for 24 hours a day, I think, a while ago, and it just didn't make sense. Maybe it does now. I am too lazy right now to wake up at like 3AM to turn it on in the morning. 256megs of ram is enough, no problems there, so long as you are running one single instance of JBT from the command line (not from within eclipse). Back when I did the math, linode was the best choice.
