I currently own a mid 2012 15" rMBP. It is the standard 8gb RAM, 2.3ghz configuration. This machine has served me well and still seems to perform up to par for what I do. I use it at this point mostly for word processing, emails, web browsing that I can't/don't want to do on my iPad/iPhone. Nothing really intensive at all. The main issue right now is the battery. It is the original battery and is starting to perform really badly. For months I've been thinking about pulling the trigger on a new 13" MBP (the 2.4 ghz model) but have recently started asking myself whether dropping $2000 would be worth it for what I use my computer for. Would I better off just saving a massive amount of money and just fixing the battery for $200 and squeezing more use out of my current 2012 rMBP? I can afford a new computer, so money is not really the issue, but saving that much money is always very attractive. Also as a third option, should I be maybe looking at a cheaper Mac like an Air or maybe a lesser MBP model? Just want to make sure I make the right decision on a potential purchase this large. Thanks in advance.
