Here is a little comparison between the new cheaper iMac and the entry lever 13" Macbook Air. The iMac is priced almost spot on with the entry 13" Macbook Air (with the iMac being priced only £50 more expensive). Let's compare them then: Screen iMac = 21.5" 1920x1080 MBA= 13.3 "1440x900 winner = easily the iMac Processor They have the same processor, but the iMac performs around 10-15% faster multicore wise. winner = iMac GPU They both have the same GPU (Intel HD 5000) winner = draw RAM iMac = 8Gb MBA = 4Gb winner = easily the iMac Storage Capacity iMac = 500Gb MBA = 128Gb winner = easily the iMac Storage Speed iMac = 100Mbps read and write MBA = 700Mbps read and 300Mbps write winner = easily the MBA This really isn't overpriced when compared to the MBA. I'd say it is a very tough chose for anyone that is looking to spend roughly £900 on a Mac (or £700 on a refurb version) and doesn't need it to be portable.
