I haven't checked out the light wallet as of yet. We were considering a web wallet as a way to get new people interested without having to use a desktop wallet. Eventually, even if you use a web wallet, you will want to use a desktop client, for higher security or storage, though there are other options here as well. Making the desktop client more user friendly will be helpful when you get to that point.
Then perhaps something as simple as a distraction while the blocks are loading. Remember Windows XP & 7 installs? There is a moving bar showing completion status but also a box with constantly changing information to read while the install continues, just to distract you from how long the install is taking!
