"I might look at the specs a bit but frankly I couldn't tell you what processor is in the one I currently have."
Oh my god, people like this are on Slashdot?!
Yes there are. We probably outnumber 'people like you'.
99% of the work I do could (and is) done on a 4 year old laptop. I can't remember what CPU is in it (AMD, Intel, TI-99?) and couldn't be bothered to look it up. If I need to know, I'll figure it out then.
When it breaks, I'll do a little research and get a new one, but since my price bracket will likely be sub $1000, I'm much more interested in how much ram is on board, does the chassis run cool, is there a built in webcam for skype calls and is the keyboard sensibly laid out (to name a few). The ergonomics and features of the system are so much more important than the CPU to me, I can't imagine spending more than an hour or so googling to make sure there are no CPU's to avoid.
The graphics workstations we purchase for the artists in the company are another matter, and I could recite the specifications for those to a ridiculous level of detail.
