I have some questions about MBP purchase: 1) what are the *real* benefits of choosing a stock laptop over a BTO one? 2) is choosing a glossy screen makes the laptop BTO ? 3) HD type: 120 GB (longitudinal) vs 160 GB (perpendicular). Is perpendicular really faster and should I really consider this factor as an important one (beside the extra space) ? Is it really confirmed that it's the case ? I just checked the forums and I haven't seen a confirmation with serial number of the HD. I don't really care for the extra storage space but if it's a matter of speed too, it becomes important. For sure, I want the glossy screen. I would also like to have no problem to repair/replace/sell/return in case of failure of the laptop so I think that avoiding BTO is better. Any toughts on that? Thanks.
