New iMac, Mac mini, MacBook etc.

HT was very important on Pentiums. It is what made Windows responsive on P4 machines. It is what made anti-viruses acceptable.

Now, what does it mean when we have 4 CPUs available ?

I kind of don't know what you're trying to say here. Yes, Pentium 4 processors had HyperThreading -- they also had extremely long pipelines (something on the order of 21 stages, while comparable G4 processors had around half that, or less), and the HyperThreading was almost required to make up for this problem -- some would even argue that it compounded the problem.

I don't know what you're trying to say when you say, "It is what made anti-viruses acceptable." Anti-virus protection and HyperThreading have nothing to do with each other at all.

What do you mean, "what does it mean?" It means that the 4 cores will appear as 8 to the system. It means that you can theoretically have 8 concurrently executing threads. What else do you want it to mean? Can you elaborate on your question a tad?

Basically, I'd stay it's a very strong iMac line-up. _All_ of the "cheaper" machines run at 3.06 or 3.33 GHz and the core i5 and i7 processors surely make those machines well-built graphics powerhouses. (Although I'd still like an inexpensive Mac Pro rather than those more expensive iMacs to fill the gap between the iMac and the Mac Pro, but that simply won't happen, it seems.)

The beautiful thing about the core i7 (which I'll choose) is that it does adapt to power requirements so nicely. It can run at very high clock speed when powering down 3 of the 4 cores, so a single task can have the power it requires - or it can run at still-very-much-decent speed on all 4 cores. It's a nice processor, design-wise. At least it seems like that to me on paper. I'll love to put it through tests.

On the other end: The white MacBook suddenly looks sweet again. Those flakey topcases (breaking plastic around the keyboard) was getting old. Now it looks like a good machine again, and inexpensive enough, too.

I wish the new mouse would work with Windows. If you are running Boot Camp and got a new mouse, how are you supposed to use it???

I wish it would work with Tiger as well.
