One of the advantages (and disadvantages) of linux applications like emacs is that you can, if you know how to, customize it to your taste so you do not have to 'learn all the tricks and features' of it. You can use cua package if you are used to C-x,C-c,C-v and other windows stuff. You can change keybindings of ESS if you do not like them.

The reason why I like ESS is that I can step through or run a piece of R code easily. For my ESS installation, I have several ESS buttons on the toolbar to start R, eval line and step, eval region and eval function. I have also linked these functions to shortcuts F9,F10,F11 by defining

  (define-key ess-mode-map  (kbd "<f9>")  (quote ess-eval-line-and-step))
  (define-key ess-mode-map  (kbd "<f10>")  (quote ess-eval-region))
  (define-key ess-mode-map  (kbd "<f11>") (quote ess-eval-buffer))
in .emacs.

I do not see any reason why an embedded R session would occupy more RAM than a standalone R session, other than the time/RAM emacs uses to color the output. This can be a problem if the output is extremely long so I usually clean the R-cmd buffer once a while.
