I've been distracting myself for the last couple of days by installing eclim: it really is pretty amazing. I have yet to use it in anger, but I'm a vim user at heart: the last few months using Eclipse have felt like I was cheating (in a particularly inefficient way: a touchpad is even less efficient than a mouse).
The alpha testing so far has taught me a lot. There was one major bug that I had never seen, and a strongly desired enhancement (that I had planned, but much longer term), both of which are now sorted. It's also given me a good idea of how others will actually use the app: not necessarily the same way that I do.
But the biggest thing it has taught me is that it's not easy enough to install an apk file. When I tried to help my friend install it on her HTC Desire, it took much longer than it should, and we ended up having to install a file manager app from the market. So my next stage will be beta, and it will be on the market: it's so much easier to just send people a url that they can install from.
