My idea is that we create a list of lightweight apps! Apps that runs fast and doesn't use a lot of resources.
I've found Opera Mini and Zeam to be good alternatives for the Browser and launcher. Also FriendCaster seems to be quite a bit faster than the official FaceBook client.
Continue the list with various really fast apps and give me more alternatives for launcher and browser.
Looks isn't really the important part here, functionality is!
