FUD ALERT
Problem is our CPU are 64 bit but more importantly the OS is 64 bit.
This means to run a 32 bit app it requires having a emulation layer for the app to run int. A 32 bit app can not run naively in a 64 bit OS so the OS emulates a 32 bit OS for it. Pretty much it adds a fair amount of over head to the program because of the emulation layer.
yes the os is 64 bit Rodimus. I can't believe how people posting rubbish comments against apple have to have such conviction in things they don't really now about.
The majority - if not the vast majority - of people running Mac OS X 10.6 Snow Leopard are running in 32-bit mode. To the person who answered the question, they can go do the following to check which OS version they are running. And Rodimus you do that too, although I doubt it that you 'll report honestly that your os runs in 32 bit.
lick on the "Apple" menu and choose "About This Mac" then click on the "More Info..." button. This will launch "System Profiler" and if you look down the left side you'll see the major categories of "Hardware", "Network" and "Software". Click on "Software" and if you're running in 32-bit mode, you'll see the line "64 bit Kernel and Extensions"? The value "no" means that you're not running in 64-bit mode.
This is the default booting mode, but you can set it to but in 64 bit.
Also 64 bit apps run in 64 bits already in a 32 bit booted system, so no real point to boot in 64 bits.

Re-writing a whole suit to be 64bit is less important at the moment that incremental software updates, anyone with any level of knowledge of software development knows that an app running bug free at 32 bit, a pretty fast one for that matter, is far better than a 64 bit one that has to be written from the bottom up and have all sorts of teething problems. It really doesn't matter almost at all to the average user what ilife is in. Heck, adobe with a much more buggy and heavier software in cs and they can get away, well almost, with 32 bi, and suddenly iphoto suffers for not being 64 bit, utter rubbish...
For any novice here, read this:
Get your new macs (or buy the new ilife) and enjoy this wonderful suite that really has no equal as a suite for lifestyle apps in any computer system on the globe. It's got even better. If you want to enjoy a faster system get an ssd and 4gb ram as standards. These are the real bottlenecks, 64 or 32 bits is negligible, If you have 2gb and an hd, 32 bit or 64 bit won't make one iota of a difference in real life, they really won't. (I am not going into cpu and gfx this time on purpose, these are important too, but relative to what you are going to be doing.)
Anyone who wants to challenge what I am saying please do not nitpick, I am well aware there are some finer nuances to what I am saying, but I am speaking here in broad lines, for some people to get to the crux of what matters for the average and the above average consumer, and for some (not all of course) power users too.
Btw, why are we having this discussion? Shouldn't Slivka's article have some information on what 32 and 64 bit means instead of throwing terms around they and posting about some bloggers who are "disappointed". Or hire someone who knows about computers to explain things. Why do you have to torture users here who don't know what this means and all of a sudden think that somehow ilife will be slower and buggy and they shouldn't upgrade.
That's the worse kind of fud.
