I am going to get a 21.5" iMac. It will primarily be used for Android, iOS, and web development, but may occasionally be used for some photoshop. Any other uses I have for it will be insignificant (such as web browsing or email)
Between the two 21.5" models on http://store.apple.com/us/buy-mac/imac, considering my primary uses for it
- Would I likely notice any performance differences?
- Should I expect the higher model to last me much longer than the lower model?
- Will the lower graphics affect my ability to use Photoshop efficiently?
