Saved $600 by buying the base model 15" because my needs are very minimal even though I was very tempted to go for the $2599 spec model which would have been overkill. I am going to actually put the $600 away in a bank account and use those funds for an upgrade 1.5 to 2 years from now to newest base model MacBook Pro. What type of depreciation is everyone expecting on the 15" Haswell MacBook Pro ? $300-$400 per year not counting taxes ? I assume if exactly 2 years from now the newest 15" has a MAJOR redesign with regards to thinner size,lower weight and 4k screen resolution that the Haswell models might drop to 50% of original selling price ? My last mac is almost 8 years old so who knows if I will really follow through with my plan to upgrade every 2 years when my warranty ends but I could be tempted if there are some massive improvements in the next 2 years.
