I agree with many of the improvements noted above, but to me the greatest overall need is the very slow speed of ALL computer actions and apps. The time it takes to sync with my current model iPhone, the time it takes to wake up screen graphics and apps, etc. i feel like i’m dealing with an 8086 computer. I own a software engineering company, and we wouldn’t dare deliver a consumer app with these overall lag times. Upgrading the computer hardware is too major at this point, but refactoring — or entirely rewriting — the software is possible and needed. No. 1 priority would be security. No. 2 would be speed.
