I can upgrade from the base i5 with base everything for the 15" i7 with matte high res screen. That would be a pretty good upgrade right? higher clock speed, more storage, higher resolution. On paper it seems like a no brainer. But is there anything less obvious I'm missing here? Everything seems obvious except the screen. Are the matte screens inferior in any ways? Is it less bright? Maybe inferior colors? Thanks for helping me make this decision guys.
