I don't understand why when I buy an App on my iPhone or iPad (Angry Birds for example) I have to buy it again (and more expensive) for it to work on my Macs... A purchased App should be compatible with all iDevices like an iTunes song...
The Retina Display on the iPhone 4 is amazing!! I would be great if the iPad could have an increased resolution. I don't think at this point the Retina resolution is achievable on iPad given the size of it screen (I would require a super powerful video card) but at least an improvement of the res.
Most tutorial free or purchased software is for Windows, XP, Vista. Please make an effort to make the existing or new software available on Macintosh OS
