That's a point for some people although I personally couldn't imagine having an ultra-portable as my only computer. I guess Apple should go with two models then. One about 1" thick with optical drive. And another one about 1/2" thick (maybe a bit more) without optical drive that could work with a desktop at home through firewire (for installing software and such).

But it's an ultraportable based on weight, not based on screen width. For example, I and many others were perfectly happy with our 12" 4:3 ratio iBooks as our only computers. My mom had no problem with it either (I gave her my iBook G4 since I was upgrading), and she's usually a stickler for having large, readable fonts and such.
To each his hown, I guess, but I don't think Apple markets *any* of its Macs as a "secondary" computer. Each Mac has to stand on its own.
Let me make this point, though: Sony, Dell, IBM, etc. have been making successful optical drive-less laptops at 3 lbs. or less for over 6 years now. Apple has had EVERY opportunity to sell a slim optical-less PowerBook all those years. Yet Apple has CONSISTENTLY determined that optical drive is an indispensable part of the Mac experience. Apple has instead decided to provide the lighest, smallest laptop WITH the constraint that it has an optical drive. Thus no one has yet been able to touch the 15" MBP at 1" thin and 5.6 lbs, or the 17" MBP at 1" think and 6.8 lbs. Apple's 15.4" MBPsare just a smidge heavier than other companies' 14" laptops, and its 17" MBPs are just a smidge heavier than other companies' 15.4" laptops.
Furthermore, Sony has moved AWAY from offering optical-less laptops, as it is now able to offer an 11" at 2.7 lbs and a 13" at 3.8 lbs. I think that Apple will follow the model of Sony circa 2006, not Sony circa 1999. If Apple can get a 12" MacBook down to 3.5 lbs. or so WITH an optical drive, then I don't think they will even entertain the idea of getting rid of it.
Sorry folks, the market is just not ready for an optical-less laptop.
