I'm typing this now on a 4.5yr old uMBP with 16GB RAM and 500GB SSD. The thing I love the most about the MB's I have owned is it seems like even at the 5yr mark they still keep up with any Windows laptop and while searching for a new laptop for my dad I was horrified to find that a lot are still in the 4-8GB range with only a few of the $800+ options offering even a lowly 128/256GB SSD. Anyone else still on a uMBP? If so, do you plan on going to a rMBP anytime soon and if so, are there any aftermarket options for RAM / storage? I know when I bought my wife's rMBP in May '15 there were none and we were "stuck" with an 8GB/128 SSD model.
