Mac OS X Earlier this week, Apple released the first developer preview of Mac OS X 10.7 Lion. At the same time, Apple listed a number of new features we hadn't yet heard about, which are quite interesting. There are two themes: bringing iOS to Mac OS X, and adding features other operating systems have had for ages - except in such a way that you can actually use them. Update: Fixed that scrolling thing. It's the other way around of course.

64-bits, damnit

"It's clearly a case of Apple trying to get you to upgrade;"

Oh come on, this is just stupid. There is a clear TECHNICAL reason that Apple is doing this --- they want the entire OS stack, OS proper and UI parts, to be 64-bit only. And who can blame them --- they've had to piss away large parts of the 2000s trying to keep the OS running, rather than adding new features, as they had to add compatibility for first PPC-64, then x86, then x86-64, then ARM. They're desperate to try to get things under control, so that they can spend time adding actual NEW FEATURES rather than just making old things work on a new processor.

By dropping x86-32 they not only simplify their support burden --- now down to two OSs --- they can, just like Snow Leopard, ship a Lion that is both more powerful than its predecessor AND takes up less space. They can concentrate their compiler efforts on schemes that will work on a 16 register chip, rather than having to worry about 8 register x86-32 compatibility.
Any SIMD code they ship still has to deal with a plethora of the various add-ons Intel ships with each new chip, but at least the number of variations is down slightly. etc etc etc.

Look, this is no surprise --- Apple has operated this way for twenty years. Most of their customers understand, accept it, and are willing to put up with the minor hassle for the perceived benefits. If it affronts your sense of the way things ought to be, I'm sorry, but they are NOT doing it just to "force you to upgrade".
