I think that would be very, very cool to see written up. I still question why we have new computers at all, to be honest, if the current hardware can run new software faster than they ran the old software.

Because things improve. Software like Adobe gets more and more demanding. We are talking OS's here and whether Lion will run as fast or faster on the MBA then Snow Leopard. Some apps though do get more and more demanding, especially games. Also it's nice to take less and less time say converting a video or compiling something and the newer faster hardware sometimes take 1/2 hour off some tasks.

Like was said earlier, no one outside developers under an NDA have Lion, so anything we can say is just a guess at this point, but I see no reason why Lion will drag on that MBA.

The thing is, Adobe gets more and more demanding not (just) for shiggles but because it's doing more with the hardware. Each new version of Adobe's products have more features than previous ones. In marketing speak it's called "taking advantage of more powerful hardware". To my eyes Puma doesn't do nearly as much as Lion and that's why I'd suspect that, keeping the hardware the same, Lion might run somewhat slower than, say, Puma (of course, in practice, Lion runs on considerably more powerful hardware than Puma does) despite all the years of work that've gone into making it as efficient as they can.

Yeah, me neither. I think benchmarks will settle it for sure but I can't see much threat of it dragging. I can't imagine anything really making this drag.

Most people who buy Macs (an overwhelming majority) never DO upgrade their computer. The last time I looked into this, it was something north of 80 percent. And by "upgrade" I mean ANY SORT of upgrade, hardware or software. Once they've bought it, that's it until the day it dies or becomes intolerably awful, then they just replace it with a brand new one.

I mean, if software gets more efficient with each version and how fast it runs doesn't depend on how big the software is, we seem to have gone from just asking if Lion runs slower than Snow Leopard on the MBA 11 to invalidating buying more than one computer in your life.
"Software" doesn't always get more efficient with each version, just Apple system software does. I can think of other operating systems that pointedly do not.

OTOH, we have to remember that we are constantly asking computers to do more things. What you were able to accomplish with 10.1 is nothing compared to what you can accomplish with 10.6.

But mostly, I don't see what you're really getting at, your conclusion doesn't seem to make any sense. How fact A (software tends to get more efficient with each version) and fact B (the size of a program doesn't necessarily have much impact on how quickly it operates) lead you to conclusion C ... I can't see any connection there.

That's kind of the thing, I think the problem you're picking up there is that C (computers don't become obsolete because they can run larger, more efficient new software faster than the software they did when you bought them) is unrealistic.

Ah, yes, that helped me understand what he was getting at, Steviesteveo. While YES, older computer can -- for a while -- run newer software and thus become more efficient over time (at least with Macs this is the case), eventually the bottleneck moves to the processor or the RAM type or some other *hardware* factor to improve efficiency, so at that point they change processors dramatically enough (such as the change to Intel) that the software has to be written for it and not the older processors, necessitating a new(er) computers.

As an example, some iPhone apps won't run on my original 2G iPhone. Most still do, but some won't (and that number is increasing all the time). Why? Because my iPhone doesn't have a dual-core processor, dual cameras, more RAM and other requirements that more recent apps require.
