I'd be interested to know why - what feature(s) in particular make you use BLIde ove the CE CE version? Although I've not used BLIde, I'm guessing it'll be down to better project management...
My main project has a fair number of includes and numerous other ancillary data files so project management and folding is a must. The directory structure is reasonably complex and organising all this without BLIde would be a nightmare. Community IDE is for code testing prior to implementation into the main project or code tests for the people who request in this forum. I think I could get away with using Community IDE for the main project if it had folding. Don't have any other projects going on at the moment.
@Gfk: I just had the same thing recently. I bought Aurora when it was first released and then a few days later the price drops 50%. Can't win...
