If you need a break from the items that are slow in v12, spend 15 minutes and create a quick image or document management DB. I'm sitting in a B&N using WiFi on my laptop and iPad, and it's hard to believe this is running on a server in another city (about a 50ms ping average.)
4G on my iPhone -- Still very nice. Scrolling is almost as fast as WiFi.
