You could write a little app that would spin up EC2 instances when you need them, and then kill them when your done. Although, I'm not sure how long you need them for to run certain jobs...could get a bit pricey after a while.

I'm looking for a 24" LCD with at least (although I don't think they get higher) 1920x1200 resolution, preferably thats under $400. I know there was the Samsung 2433BW, but the current trend tends to be 1920x1080 set as the standard and then charging a premium ($500+) for anything higher.
Any...
