I was just windering...what's the average depreciation of a MBP over a year? If I purchase a new 15inch rMBP for $2700 today...what do you think it would sell for by next August (assuming that's the date of the new release)? If I were to take this approach, which I think I may...I'm thinking it may make more sense to upgrade to a 512 ssd, as it seems there will probably be a higher demand (when combined with teh 16RAM) as there are probably a LOT less of them then most other builds. What does everyione else think? I'm just thinking about it...If I buy a computer for $2,500 every 5 years, wouldn't it just make more sense to take a $500 hit every year and just keep upgrading at release? Looking at this from a more economical standpoint, I think the most economical approach one could take, would be always purchase LAST years model, and continually pay $300 or so to upgrade every year (which would essentially mean that you would always be one year behind in models). Opinions?
