Wasn't sure whether to post this here or in the Marketplace. I opted here as I am not selling or even close to selling right now, it's more a general enquiry based on past experience of other MBPs. If anyone feels this would be more appropriate in the marketplace despite my reasoning then please feel free to move it etc. Anyway, I'm curious how well previous generation Macs hold their value when a new generation is released and if anybody can give me some estimated figures on how much the value drops. For example, I bought my MBPR via education discount for £1500 which includes a standard free three year warranty in the UK, plus my MBPR also has a Samsung display with no IR. Considering without student discount the base model retails for £1800. Do you think when the Haswell MBPR is released, I would be able to sell this MBPR for c. £1400-1500 [bearing in mind the 2 years guarantee included plus Samsung display] or do prices depreciate faster than that?
