If you're using powdered detergent, make sure yours doesn't have zeolite as the water softening agent. It will deposit in the machine, and starts eventually covering the fabrics with a talcum-like powdery substance. It gets especially bad if you either have to use a lot of detergent because of hard water, or are overusing the detergent.
Zeolite was brought in to replace phosphates due to environmental concerns, but it has its own problems with the washing results.
One other thing that often ruins the freshness of clothes for me is overly scented/perfumed detergent. The smell can get quite overwhelming, and contribute to a chemical-y smell and feel.
I wouldn't call OLED a minor upgrade – considerably better battery life and color rendering. Also better blacks without background bleed, which is a major annoyance when gaming in dark (bus, plane, bedroom etc.)
800p is for a good reason – although e.g. 1080p would be more crisp, personally I'd pick better colors and higher refresh rate over resolution in this case. When gaming with the APU, most games (especially AAA) can't be upped to 1080p either way without considerable performance drop. I kinda understand the need for higher resolutions from a strategy gaming standpoint, but to me at least the compromise isn't worth it.
When PPI is considered with standard viewing distance, it's still better than my 1080p 13" laptop. With proper anti-aliasing there's no need to push it further, at least IMO it's not worth it compared to the reduced performance.
2560x1600 would make a bit more sense, as you could drop the resolution to 1280x800 without having to smear pixels due to pixels not lining up in the smaller resolution. That would also be better for strategy games. Don't really know how good the panel availability for those is, though, since it's probably using a tablet screen.
