My concerns really relate to the current F/X rate. 15" rMBP's are currently around ~ $500 cheaper in Canada then in the US due to the huge drop in C$ value vs USD I have an early 2013 15" rMBP 2.4 GHz Core i7 with 16GB RAM and 768GB SSD. Apple care is valid till March 2016 I can get on average ~ USD $1800 on eBay based on sold listings. A new machine with the specs that I want will run me USD 2030 at the current USD/CAD F/X (including taxes). Factoring in eBay fees it would cost me ~ USD $400 to upgrade. There is no doubt that Apple will raise CAD prices shortly and definitely at the next upgrade cycle. So the question is. Is it worth it to upgrade now? Any feedback is much appreciated.
