I never considered it because I can't think of a problem I need a mainframe for. If there is something really CPU intensive I would use the cloud (map-reduce XYZ) for it. Have you ever come over a discussion here on HN and someone said "Let's use a mainframe for that"? I know there are a few disciplines is science where it is important, but then I would have an interest in meteorology etc. to even consider it. So all the rest I associate with legacy stuff, where I heard horror stories from people. Never "Wow that AS/400 is so cool for X".
