Unacceptable to who? I just don't get it. I needed a more powerful machine for work a over a year ago so I bought the a Mac Pro. When the Quad option became available I thought, that's nice, but I really don't need the extra speed. The next machines we bought were the fast machines, but I still kept my "old" computer. Why, because honestly it didn't make a huge difference.
Do people who say things like the above comment even buy these products and use them in the real world? I'm just curious. You know you could have the fastest CPUs in the world, but if you're just using the computer to surf the web, check e-mails and use iTunes, does it really make a difference?
