I'd prefer a Macbook Pro to a desktop anyday. Sure with the same priced models, you got more processing power with a desktop but you lose mobility, convenience, and of course you need to have a monitor. As a business professional i'm taking my lap top everywhere. To pitches, presentations, meetings, traveling, even to Starbucks when i need a chance of atmosphere. The new Macbook Pro's are upgradeable to 4GB RAM, and have the new chips in them so they are pretty darn powerful. Of course if we could all afford it we'd get both, a desktop at home, and laptop...nevertheless if i had to pick one, i'd definitely go for the laptop. Also you can get pretty good double monitors fairly inexpensive, and since the Macbook Pro has the dual DVI's it's no problem...in fact the MBP's have better graphics cards than the desktops.
Thanks K1M and dot1q,
I'm still wrestling between upgrading my PowerMac G5 to a Mac Pro or going mobile and getting a MacBook Pro (keeping the G5 around for a few more years....)
I agree with both of you on the points both of you made. I found with my old PowerBook, it was exactly as dot1q said -- it got to the point where I wasn't using it for anything "productive". The screen space was much too small and over the years, the G4 really started showing its age. But, like K1M said, its nice being able to go to a coffee shop to meet clients, or doing work on the way to school...
I am on FaceBook. Ninja mode, tho. So PM me with your details and I'll add you ;D
