you know my preferences, i guess heheh ;) i used to swear by pp, but now addicted to p6. i'm personally pondering continued support for p4 (for stand-alone stuff, depending on how poly-heavy the product is). i'm guessing that those still using p4 are the one with older computers that cannot meet the requirements for p5/p6. no reason not to support p4 unless the product requires high computer resources to use, i think. good poll, tho :)
