On the other hand, the current MacBook Pro line is quite mature which translates to stability and lack of grievous hardware or firmware issues. I'm still wary of buying a first generation Mac product after my experience purchasing a newly-unveiled Macbook (white body) in June 2006. Between the dirty-looking discoloration of the plastic and the random auto-shutdown firmware bug that bricked my new laptop in the middle of the firmware update to remedy aforementioned bug I was very unhappy with my early experience. It turned out to be a great computer after the bugs were ironed out, but I'd still rather avoid repeating the experience.
Is there any innovation expected in the MacBook Pro line that will be that much of a leapfrog over the current incarnations? I'm wanting to buy a new development laptop in the next two months as well and I can't see anything other than a better form factor coming out of the next generation.
