A few of the highlights:
- The browser matters. Firefox is faster than Internet Explorer, and enabling Adblocker will save you precious time as well.
- Don't email full size photos. Use a tool like Microsoft's Image Resizer, since digital images can be many megabytes more than the recipient needs.
- Disable automatic updates. Let me point out that in general, disabling automatic software updates -- like Microsoft's Windows Updates -- is a horrifically bad idea. But if you're trying to get online work done on a very slow wireless connection, then you might want to temporarily disable it, as long as you make a habit of turning it back on later.
