1. Almost all smartphones sold today have the same two flaws — and the cases you’re buying prove it. Durability and battery life. Battery life is always in the news. This is a good reminder that durability is important too. The question is, for the next $1 of R&D to spend, do you allocate it to optimizing durability? Tough call, but most might answer “no”.

(Correction: I don’t think I should have framed it that way. It really depends on what other features you’ve developed and what parts of the product you’re able to control. And, crucially, the degree of improvement you’re able to make.)

2. Why 8 and 10 CPU cores in smartphones are a good idea – a lesson from the kitchen. (Remember, not every company is in a position to optimize its own CPU.) The main point:

The clusters of cores have different performance and power characteristics. With clever scheduling the mobile OS is able to use the best core for the best job […] more cores equals […] better power efficiency, but not necessarily more performance.

5. Why the Verizon-AOL deal just might work: Mobile video ads are worth a lot. “Verizon didn’t buy AOL, a dying ISP—it bought AOL, a digital ad company.” Maybe because of this.
