Peggle for PC is still available for $10. It's the same price on the Xbox 360 (Live Arcade).
The iPhone version is $5.
Are you telling me that you would rather sit in your living room playing Peggle on your iPhone to save $5? Seriously?? Well, that is your prerogative, but don't come complaining back here when you've gone blind and cross-eyed from starring at a 2" screen and have carpal tunnel syndrome.
It's worth the $5 extra dollars, to me, to be able to play it on an HD big screen and hear it on 5.1 surround sound while sitting comfortably in my living room using a much more comfortable ergonomically designed controller. Not to mention XBLive with friends and game achievements.
I'd pay the $10 for a console arcade game. I would not purchase any phone games at ANY price, except the ones that I've had for free, and those I've only played once or twice. But that's me. Playing a game that I can barely see, hardly hear, and cramps my hand in the process does not interest me in the least.
My leisure time comfort is worth much more to me than $5, but please, feel free to go knock yourself out. 8^b
