Give me a call when you can buy an 8 core Xeon Macbook Pro with 32gb RAM.
People, I am talking laptop vs desktop - not laptop vs servers. And besides a mac pro is just way overkill, unless you are running it as a server or doing massive video production (which hogs CPU and memory while rendering) as in running a studio. Would I love a mac pro, yes - but it is way over kill for my needs. I would love a lexus or cadillac - but for needs my Hyundai Elantra does just fine. I won't bring my wife's car into the picture - Honda Fits may be inexpensive, but they are snappy and versitle.
For most persons a macbook or macbook pro has enough power to do everything an imac can. A mini - well a baseline has a lower CPU but with the way OSX operates I have yet to have any complaints out of it. But my macbook is faster. And besides we are talking apple technology.
If we were talking about Windows PC's. Well, then it is up in the air. really. Most lower end PC laptops stink and you can barely run 2 apps without the thing coming to a crawl. the mid to higher end laptop PC's will get you some good performance. Desktop PC's are the same way. Lower end desktops are actually worse than a higher end laptop in performance.
I know, I had been using PC's since the 1980's. the first computer I was introduced to in school was an Apple IIe and it blew away the then IBM compatible Zeniths we were using (graphics and apps - anyone remember visicalc for spreadsheets) or the trash 80's by radio shack. I even wanted an apple back then.
But along came commodore 64, and the whole MS windows explosion. You could not find an apple computer anywhere and anyone who had one complained they were slow and the apps were lacking. I know someone who has been using Apple for the last 10-12 years (maybe more). he said before OSX, Apples were just pathetic. Now, they are the best computer you can buy.
Now in 2008, Apple makes it so that I do not need a desktop. Personally, I think the imac/mini of a desktop. to me the mac pro is a low end server or a way over the top tower needed to run studios.
I guess 28 yrs of dealing with Windows/PC technologies has warped my mind (I started playing with computers when I was 12). Don't worry a year or so dealing with Apple and my mind will be strait again. Atleast I will never see another BSOD just from plugging in a drive or a USB peripheral.
