They broke about 99% of the keybindings, however you can use a 2.79 keybinding set. The new tools on the left are 100% useless to me, but I have been testing 2.8 for about a month or 2 now and have gotten used to it. Yes I still use RMB select. If you swap to LMB select the entire functionality of RMB select isn't copied over to LMB select, it a totally different thing. This is really annoying, but one of the few bad things about 2.8.

I was a bit worried about some of that missing functionality - just turned it back to RMB - and yeah, you're absolutely right. I thought stuff like alt-click not working was me just losing my mind. I wanted to learn the new stuff just because I don't want to end up bound to a bunch of input conventions that will end up depreciated - and I don't really care that much about LMB and RMB, or indeed any of the old blender UI, but I don't want to start using the tools on the left, since they are, as you say, useless. I'm more a 'select things, do an operation on them' kinda guy, so using a tool in edit mode (with a few exceptions) is kinda neither here nor there.
