Would you consider using one of the trackpads you're happy with INSTEAD of a mouse? For non-precision work, that is. Browsing, navigating an IDE, clicking around the OS, stuff like that. In an emergency anything that does a two finger scroll and registers a click is okay, but would you enjoy using it for eight hours every day? Apple will confidently sell you a $5000 desktop machine with just their trackpad, because it is that good.
