I think I have a problem with the word obsolete. Plenty of people are still going to have and be using 32-bit processors for years to come.
Do you really think that with all the 32-bit processors out there that Leopard is going to be optimized for 64-bit processors that have been out for half a year?!? (Assuming 10.5 comes out in Jan '07). Apple is going to have to support G5's for several more years and you think they are going to phase out the 32-bit Intels right away? People are still buying G4 iBooks now that is an "obsolete" chip (or at least it should be).
Finally, what are the real world difference we will see going from 32-bit computing to 64-bit both short term and long term. Here is a pretty good article on that.
The answer is that it depends on what you do and what programs you run. Long term 64-bit is the future, I don't think anyone is arguing that. However, by the time there is enough true 64-bit stuff out there to make a difference to the average consumer, a laptop bought now will be out-dated anyhow. Graphics, ports, processor speed, etc. will all have been surpassed in the few years it will take for that to happen. This is why, the PowerMac which is Apple only truly upgradable system is probably the only one that has to wait for the Merom to come out.
There will be a day when people with the Intel 32-bit processors cannot buy new software or run the latest OS. Of course, first those with G4s, then G5s will be out of luck. It will take time. The existence of 64-bit processors doesn't mean that all 32-bit computers should be thrown out the window and all 32-bit applications will cease to exist.
As some one who bought a used IIx just before the first PowerPC's started coming out (I wasn't in tune with what was next in the computing world, I just need something to run Quark Xpress and Illustrator on), I can speak to having an "obsolete" computer. But, it did what I needed it to do and I managed to use it for five years until I got a firewire iMac. So to say that a MacBook (theorectically speaking) that came out today is somehow useless in three months it is simply not true.
