People and their CD drives are just hilarious.
I don't take you seriously and neither does anyone else. You don't need it.
If you happen to be a rare case, where you needed optical every day, all day, then fine, your 1 and 10,000,000 case is noted. BUY AN EXTERNAL.
Its not complicated at all. Get a better machine thats designed without the stupid useless optical drive, and buy a USB device for your once-a-month disc drive needs.
No one has ever offered a valid opinion on why we still need these drives. People scream, "Internet!" as if that has something to do with why we need optical drives. Everyone has access to internet. If you don't, at all, then you're simply not in a situation where you're doing much with your computer....and you certainly don't need something modern.
Crazy whiners who whine just to whine. Keep watching your DVD of Caddyshack for the 100th time.
WTF is a "a valid opinion" ? By their very nature, opinions are only valid if you happen to agree with them.
But here's a few that are valid to me:
If I buy boxed software at a store (yes, rare for Mac software), it's probably going to have DVDs or CDs in it. I have yet to see boxed software ship with a USB stick. That applies to PC games used in Windows on a Mac as well. It certainly applies to the hundreds of games and other software I already have here on DVD or CD (many of which are copy-protected and so certain breaking steps are needed to move them to another medium, yet that is also illegal under the DMCA).
Logic Studio came on 8 DVDs. That's a pretty expensive equivalent USB stick for Apple to ship it on an a pretty darn long download to get off the Internet (i.e. over 40GB). More to the point, I already have it on DVD.
If I want to burn a CD for a friend who only has a CD player in their car (not everyone has USB in the car thus far), I'm going to have a hard time doing that without a drive. Similar arguments apply for encoding DVDs and moving your CD collection (assuming you own one; mine is over 300 CDs) to iTunes. Perhaps you've already done that, but not everyone has.
If I want to ship a home movie to a friend, it costs me pennies to burn a DVD-R disc. It does not cost pennies to make a USB stick nor will that play directly on their DVD or BD player.
Whats to understand? You compared a glass of water in the desert to that of a glass of water in the sea. The sea is a desert, just a different kind.
Tell that to the cruise lines. They desalinate water in the ocean just fine. You can't desalinate sand and drink it, but even any private boat with a kitchen on it could make clean water with a few basic homemade modifications to a basic boiling pan. Better start looking for a cactus.
BTW, water does help to keep the body cool, even in a desert (the whole purpose of sweating is for cooling purposes and one of the major causes of fast dehydration in a desert environment. Ask anyone who has lived in Arizona how great sweating works in a dry environment. I was quite comfortable at over 100 degrees whereas 75 in a very humid environment can be miserable. You do need to replenish what you sweat out, though.
