The "boring problem" that always needs more attention than it gets is performance. Plenty of companies ship features that only reduce performance by 10,20,50 milliseconds but it all adds up and applications end up feeling very sluggish. Apple is one of the few where I feel like the perf doesn't regress over time (likely because the features don't really expand much either).
