Mac OS is a whole lot more efficient that Windows!
My main computer is a Mac Pro Quad Xeon with 6Gb Ram and 3TB of storage hooked up to a Dell 2407 monitor but I also have an iBook (12", 1.33GHz, upgraded to 1.5Gb Ram and a 250GB hard drive) (again see my site) plus a Mac mini, dual pentium 3GHz PC, etc etc etc etc.
The reason I mention these is so that I can do a comparison. My Mac pro is blindingly fast and does pretty much everything in CS3 instantly. Now the iBook has the advantage of extreme portability so I will take it to work or out and about. I can still use CS3 on it and it is still VERY usable. YES a 1.33GHz single core with 1.5Gb and it runs CS3 faultlessly without any speed problems. It just goes to show how good Mac OS is !
Although I think it is absolutely great I will probably be selling it as I have been saving up for a 17" Macbook Pro with 1920x1200 screen which I hope to get next month. It'll be a right corker! especially when I upgrade it to 4Gb and stick a 500Gb hard drive in it. (or do I wait till summer for the QUAD cord macbook pro that it rather likely!).
I did mention earlier in the thread my new web site - IT IS NOT YET FIT FOR PUBLIC SCRUTINY but I will give you lot a sneak preview and mention it again -

I am not a Mac fan boy or anti PC. I have a very powerful PC and have owned a PC since the 286 was a boy but having switched about 18 months ago none of my PCs get much of an outing! In fact I have just totally re-built a Compaq laptop which I will probably be selling too!
Anyway the best advice is get yourself down to an Apple shop and really give one a decent try. Take your camera and give it some welly! Does it do what you want?
The question has been asked about Mac Pro v iMac well the Mac pro is EIGHT core against DUAL core for the iMac (this make a difference in CS3) - yes I know you can downgrade to a Quad core!
The memory is highly expandable (see my sight) on the Mac Pro (up to 32Gb on ANY Mac pro) - On the iMac you get 2 slots so you have to bin the included ram to upgrade and cannot upgrade again without binning the memory you bought! (maximum 4Gb)
There are 4 hard drive bays (5 if you look at my site) on the Mac Pro so you can buy it with the smallest drive and VERY easily install at least 3 more drives without any problems at all. (You can even use one to boot windows with the included bootcamp software)
There are 2 optical drive bay using standard 5.25" drives so you can fit either another IDE drive (or a SATA drive if you see my site) - this includes a standard blu-ray drive.
You can you 2 2560x1600 30" monitors off the standard graphics card on the Pro and choose your monitors
You can add further PCI-E internal upgrade cards to the Pro.
I would like to see something between the mini and the pro maybe just the Apple Mac ! with maybe 2 drive bays and an optical bay plus 4 DDR2 slots and a single processor socket containing a Quad core processor!
The Objective: Just take the operating system for example. Do a quick Google of Vista vs. Leopard. IT bloggers the internet over give Leopard the edge (and many give a whole lot more than just an edge). There are countless other smaller points, but let's face it, the OS is the platform on which the computer runs and Apple's old OS (Tiger) was arguably ahead of Vista... and then they launched Leopard...
Oh and I will be doing a how-to comparison chart with XP, Vista, Tiger and Leopard explaining how to do all manner of different things on all 4 OSes to make changing much easier. Things like printing to a network printer; installing a printer; formatting a hard drive; copy, move and delete; permissions etc etc etc.....
