I would disagree on the differences being marginal -- I used to own a 13" rMBP and have moved to a 15" 1080p laptop and the differences are very overt to me, particularly during productivity tasks like say writing code or using something like InDesign. When objects on the screen are nice and large it's less different, but when you're dealing with smaller text it's a big diff and images look much more crisp on HiDPI screens.jetenginejesus wrote: ↑ For sure, I get that 4k is "sharper", but TBH on, like, a 14" or 15" screen, I've only noticed very marginal differences between "retina" screens and regular ol' FHD screens at my normal viewing distance of, what, 16"-18"?
I see the benefit of running a strict 2x scale, as opposed to some mid-range scale like 133.3% 1080 > 1440, but I guess I'm not getting why you'd buy something with a 4k screen only to run everything at 2x? Doesn't that negate the only real, clear benefit of 4k -- more usable space?
If the diff for you is not very big or you're not looking at primarily small-things-on-screen productivity tasks, then you probably don't need the 4K.
Yeah I double-checked and looks like you do lose more, it's something like 8 hours on the 4K vs. 12 on the 1080p for productivity. If you're gaming then yeah I'd expect more battery loss especially if you're rendering at 4K. Apologies for the confusion, I was basing my numbers off an older model I think.
