I really enjoy using TextMate, especially for the support of snippets I use for live coding sessions while teaching. I know that every thing is feasible with Emacs, but did not have time nor energy for implementing such a nice snippet management system (I only used skeletons with dynamic abbrev). Yesterday, I came accross YASnippet and found it providing the same support as TextMate for snippets. Together with pair-mode it is again a great pleasure to be back with emacs full-time.
Thanks a lot pluskid!
