I'd rather have space than SSD speed for the associated price. I want to be able to watch DVDs or burn off a quick disk. I don't want to have to step up to a bulky 15" machine just to retain these features.
The Air is not, in my opinion, a really useful machine.
So you say, well, your DVD will be 'in the cloud'. Never mind that pushing that much data up most connections will take all month, how will he even get it onto his computer with no optical drive in the first place?
Well, you might say, all your new stuff will be on the cloud, so don't worry about it. But consider if he has a massive DVD collection. Heck, not even a massive one, just assume a hundred or s DVDs.... are you Seriously proposing that he repurchase all that media in 'cloud' format? At $30 a pop, that would easily justify the cost of going for a more expensive MBP rather than a crippled Air.
Oh you say, well if it is just a matter of money, you can just buy the external optical drive. But now whenever you take the laptop anywhere, you have peripherals to drag along with you, and that involves logistics. Again, he's better off with the one that is just built in.
Disclaimer: personally I think the Air is pretty neat. I just don't agree with parent's assertion that optical drives are unnecessary.
The parent did not assert optical drives were unnecessary. He only suggested they may not be necessary for that person.
Burning CDs full of data is already an idea long gone with the advent of various flash devices. Practically no one burns CDs of music anymore since CD players are pretty much gone. Even DVDs are fading; Apple has a vested interest in this happening faster since they sell media online in any case.
With high-speed I/O, an external drive would work just fine for folks who need to read or burn disks only occasionally. These days, that's most people.
