But the MBA is a total different story. This thing should be ultra portable, as light and small as possible and with no moving parts. Totally get it to strip out the drive. It's basically an iPad with keyboard and Mac OSX.
The Mac Mini on the other hand is a desktop. Sure small and portable but a desktop nonetheless. And an almost perfect mediacenter for your TV. It just doesn't make sense (from my standpoint) to remove the drive. It didn't make it smaller, it didn't make it more usable.
Adding in a Blu-ray drive would have made sense but will never happen (I know). It's all about moving to the digital downloadable content age. Sure it's the future. I surely agree. Mac App Store is great. iTunes music, pretty good to, although audio lovers will agree that the quality is subpar. iTunes movies? Non existent in my country. iBooks? Same. And the quality is unsurpassed which is totally understandable given that a normal Blu-Ray movie is 35-45 gigs in size. Try to stream or store that. 15 movies and your HD is full. I'm a real movie lover and can fully enjoy the small details in sound and images you see in Blu-Ray that you'll miss in HD rips or compressed iTunes content.
And don't say you can't tell the difference. Anyone that I ever shown a compressed version of a HD movie (but still HD) and the BR disc saw the difference immediately. It's like a car. If you drive in your Ford it's great and gets you there smoothly. Make the same ride in a Mercedes and it still gets you there. But you will notice the difference even blindfolded .
