>>2 does have a point, though. Apple's products as of late - earlier than that some would say - are notoriously tightly controlled. The worst instance of this is customization, but lately I'm changing my opinion to it being "application approval." Unless it's approved by Apple you can't run it. There's no hardware reason a number of things couldn't potentially be run on it; the only thing stopping those is the stroke of a digital monitor which says "Maybe, but not letting you."
I'm not sure what his second point was trying to get at - "You're not missing anything?" Thanks mom... - but his fourth point is not entirely convincing since it only addresses videos again. I understand his battery concerns but should worries such as that be left to the user? As for point five: have the iPad pipe its touchscreen system to produce normal mouse-like input; provide an innate cheap mouse driver adapter. Flash will be happy it has mouse input; something. It's not like means around this complication can't be written.
The only point I really agree with is 3. Flash does have poor security and performance from time to time. Just because "Flash has not performed well on mobile devices" doesn't mean you should bar your user base from trying.
