One is so unlike the other that a comparison is not feasible.
For example, one can run Final Cut Pro HD and the other can't.
And if you know laptops, you don't want an i7 laptop unless it's used as a desktop.
I do a lot of AVCHD video editing and I have narrowed my laptop choice down to 2 and cant decide which one to get:
1) 15" Macbook Pro
Intel Core i5
4 GB Memory
320 GB Hard Drive 5400rpm
NVIDIA GeForce GT 330M with 256MB
2) 16.4" Vaio F Series
Intel? Core? Quad i7-740QM processor
320 GB Hard Drive 7200 rpm
6 GB RAM
NVIDIA? GeForce? GT 425M GPU (1GB VRAM)
