...to get a laptop.
First I would like to thank you guys for the VERY intelligent comments. Regardless of your position this is a good natured and spirited and educational discussion. Thank you. And it has helped.
When I said I was not a techie I did'nt realize how bad I really am! I got a pc and went to the Ubuntu website like some of you suggested and tried to download the free software. They made it sound so simple. No problem, right? NOT!! I could not even do that.
After spending over an hour in disbelief, I stormed out of the room wondering if I am not really non est factum.
My time is valuable, very. Unfortunately, I am extremely curious about what I do not know. I want to learn but do not have access to people who know what they are doing and prepared to teach me. My frustration tolerance has been sorely tested trying to learn from the liturature but I find that it leaves alot out. Very difficult to understand for a non-techie. It may be that I have to bite my tongue and give up in this area.
I have found in my research that Goomer is right: comparable machines to the Mac Pro are indeed as expensive if not more. Yes I can get in to the laptop market by getting a Toshiba with intel T4200 or 4300, 4Gig ram, 320Gig hard drive, update to Windows 7, 801.11n, HDMI(?), 16in screen, full keyboard for $699 + tax. But even I can tell that the engineering does not compare to a mac, software or hardware. And I am still with windows. I guess the question to myself is, do I want (do not need) the Mercedes or do I get the chevy? Yor're right only I can answer. What I want to do is learn Linux/Ubuntu but that appears to be out of the question when I return to reality. The money is there for the Mac and I am leaning heavily to treating myself. I can satisfy my curiosity and learn a new system and maybe in the process rectify myself of some ignorance without too much frustration. Yup, it's the Mac!
Profound thanks for your input and offers of help (especially Goomer); your offer of help is truly exceptional.
P.S. This is also revealing: what is the difference between Linux and Unix? Are they interchangeable terms?
