Steve, you are about where I was two years ago when I first bought a 13" MB just so I could be genuinely informed about both platforms. I found that I quite enjoyed being 'platform agnostic' and I enjoy both for their strengths. I now have a MBP 15" i7 and find it to be a superb laptop for the road and for presenting seminars. Its also, shock, good value as a laptop. I wish I could say the same about the Mac Pro, which is why I have a W7 box as my main machine.
I think you too will enjoy using both platforms.
Thanks for the response Nick. I'll get there. Maybe. Every time I get an itch to try Mac I start researching a bit and then find PC hardware more suited to my needs. As an example: Last year I wanted a small field expedient computer 'device' to use for time lapse, focus bracketing, very long exposures, and exposure bracketing automation. It also needed to be fairly weather proof. Immediately the Ipad came to mind. After learning it didn't support any of the software I needed, the actual computing power was quite low, to expand the storage was Apple only, spare batteries weren't possible (a must for what I was planning).. I then started looking at netbooks and eventually ended up with my x201s Lenovo. I didn't look at cost so much, but at function, power, size, weight, and weather resistance. Netbooks ranged from 2.6-3 pounds. My x201s was 2.4 pounds. Sure, it cost a lot more, but my priorities were function/fit to my tasks, not price.
Another example: 3 years ago I ordered both a 17" MBP and a 17" Dell Precision Workstation. I ran them side by side for over two weeks and sent the Mac back. It's screen and graphics card weren't in the same league.
Now.. I think the MBP 15 and 17" models have improved quite a bit.. very competitive from a hardware point of view. In a few months I'll be replacing my 17" Dell Precision Workstation and once again I'll compare it to the MBP 17".. and maybe a Lenovo as I've been impressed with them lately. The W series are photographer centric.
My wife was hinting at me replacing her 12" laptop.. a base Pentium M machine she's had for years. Mac doesn't seem to have anything in 12 inches.. and she wants 12 inches.
I'm very interested in setting up an additional SSD on my main PC workstation to run Snow Dwarf from a Hackintosh config. Mac makes a nice large external trackpad so I could get the full experience. Swapping in one SSD for PC work, another for Mac work.. sounds ideal. I need to investigate this more.
Sorry for the verbosity.. but I wanted to show where my mind is on this. I think a lot of this comes down to Mac offering very little choice, and I'm the kind of person who likes to closely tailor my equipment for my needs and I don't mind spending a bit more to do it.
