I'll be purchasing a 15' MBP shortly and was curious to know if the Hi-Res screen is worth paying the extra $100+. I spoke with a sales rep at Apple store and she couldn't give me a clear answer to the advantages. She mentioned that hooking the MBP to a LCD TV will elimate a black boarder with the HI-RES option?? Furthermore, does the HI-RES option improve picture quality much like 720p to 1080p on a TV would? I will most likely hook my MBP to a 22' monitor and occationally a LCD TV when stationed at my office. Any thoughts?
