you can easily insert all these symbols in emacs. By default, you press 【Ctrl+x 8 Enter ↵】 then type the full Unicode name (press Tab ↹ for name completion, use
* for wildcard) Rather very tedious.
But you can trivially set your keyboard to type some frequently used unicode symbols. There are more than 2 ways, and they are trivially simple. But still not many people know about them. Simplest method is:
(global-set-key (kbd "<f9> a") "α")
you can also use abbrev, and other ways, each has some pro ＆ cons. See How to Create a APL or Math Symbols Keyboard Layout ⌨
few months ago we (the emacs community) had a emacs conference. Sacha Chua has helped tremendously to make it a success.
She also made lots of wonderful drawings, a summary for each presentation. See at http://sachachua.com/blog/2013/04/emacs-conference-2013-sketchnotes-also-pdf/
also, videos are collected, at her youtube channel at https://www.youtube.com/user/sachactube/videos
lots videos, including chats with many prominent coders. So, bookmark, and visit at leisure.
if you need to remap your keys, see: Mac OS X: Keyboard Layout, Keymapping, Keybinding, Software ⌨ (there's links at bottom to Linux or Window tools.)

Emacs Keybinding Design: beginning-of-line-or-block
on reddit: Nearly everyone who is new to Emacs hates it passionately — how do we fix this?. Here's my comment:
make it work out of the box for them. Make the 7 or so standard keys: copy, cut, paste, select all, open, close, undo, redo. Turn on cua-mode by default is a semi answer, because it doesn't support many of these keys and it conflict with emacs keys. Just get gnu emacs dev to set emacs C-x C-c keys to something else. It's pretty easy to implement, the hard part is how not to get flamed to death whenever this topic comes up every month.
as long as emacs is the way it is, it'll never grow out of the heavy geek circle.
if emacs adopt these keys, emacs power remains untouched, its keys actually becomes more efficient and less RSI, and most other editors such as sublime etc etc, will extinct overnight.
2 tips i stole from Phil Hagelberg's Emacs Better Defaults setup. https://github.com/technomancy/better-defaults/blob/master/better-defaults.el.
;; when pasting with middle click in Linux X11, set to paste at cursor position, not at click position (setq mouse-yank-at-point t) (setq ido-enable-flex-matching t)
the mouse-yank-at-point i wanted for a while. The ido-enable-flex-matching i'll wait and see.

the Microsoft batman keyboard is out. See a hands-on review by Øystein E Krog (in the comment) Microsoft Sculpt Ergonomic Keyboard Review
Matt's been working hard on all sorts of improvement and features for ergoemacs-mode. He's adding code every day. One of the latest feature is dropping dependency on
cua-mode. ergoemacs-mode implements its own 【Ctrl+c】 key for copy, and others, as well as several options you can setup. (it's a necessary move, because ergoemacs-mode is restructuring the whole keybinding and cua-mode gets in the way.)

i highly recommend the package: “highlight-symbol”. It can be used as a substitute for isearch. See: Emacs's Incremental Search (isearch) Problems (updated)
my glorious coding career is before me. I have a vision, how my fingers is gonna rule the world. But RSI fscked me up.
do you have any idea who'd be the top 10 most emacs lisp expert in the world?
It's a interesting question. But if we narrow down to emacs keybinding system, i think Matthew L Fidler would be one of them. The ergoemacs-mode engine he implemented, dives into the depth of emacs's key system in order to get the keys right for you.
