I am about to build a new system based on your DIY7.7 recommendations. However, before I do, can anyone tell me whether the new Qosmio laptops from Toshiba with the Intel Core i7 (720 or 920), a 500GB HDD and 6GB DDR3 (two memory slots) work for video editing?
I would suspect it would "work" if the video card was good enough and compatible. (most in laptops' video chip-sets are pretty weak).
with that said-- I would never use a laptop as my main editor for projects.
If I was on the road and need a quick & simple project edited on-site because of special circumstances, then I would find myself getting an appropriate laptop for my NLE software.
