So here's my predicament: my wallet says to go with the cheapest base refurb rMBP that's available, while my gut says to spend a little more for additional value later. I'm using a 2008 Core 2 Duo MBP (pre-Unibody) now that was sort of the "typical" configuration for the time (dual core, 2 GB RAM), and it ran things very well then, but now struggles just to open Photoshop, switch Firefox tabs, or even play YouTube videos. Would it be wise to go a little overboard on the configuration on one of these to get some more years out of it (ie 16GB RAM and the 512 SSD upgrade)? To be honest, as a journalist by trade, it's rather overkill for most of what I do now (which does include some light photo editing, Lightroom, and a little light video editing), but what about in 5-6 years? Is the base config potent enough to run like a champ for years, or am I going to wish I'd splurged for more when it starts getting long in the tooth?
