You do know any laptop you buy is obsolete the minute you buy it right?
Nope.. because they are upgradable.. try again.
You do know some people DO work at full 2800*1800 resolution?
No, I don't know anyone who works in 2800x1800 on a 15" display because the text and everything super tiny. So it's useless. Plus benchmarks show that if you run your Mac Book Pro retina with that resolution everything is beyond slow, especially videos because GPU can't keep up.
You also know you can drive multiple displays with the retina mbp he(Spirit Dave) has?
So? So does every other computer and laptop. The point is that he doesn't get retina.. so it's again useless.
You also know that you dont have to go into EVERY APPLE THREAD and spew your bull**** everywhere, right?
Take you insults somewhere else and learn some manners since your parents obviously haven't taught you any.
Also, if you think retina is hype, then you should NOT own ANY high PPI devices be it a display or a smartphone. But thats bull**** because guess what? A lot of smartphone manufacturers are focusing at higher PPI devices. (Droid DNA with 440 ppi @ 1080 in 5" screen)
Because there's a difference between a consumer level device like a phone or a tablet because they are fairly small screens and increased resolution actually has a purpose since they are content consuming devices. To make everything crisper and cleaner and it's for actual consuming content not creating. And it's completely different because it works differently as far as density goes.
And yes.. a 2560x1600 display on a 10" tablet is an overkill as well. There is no visible benefit over 1920x1200 for example. There's a threshold where you actually see a benefit.
