Place touch into restore mode by holding “power” and “home” keys until it resets.
Release “power” button after screen goes black; keep the “home” key pressed until iTunes notices.
Option key + click “restore” in iTunes, it will prompt with an open file dialogue window, you can now select the firmware file
Well I was such a little fanboi that I’ve got leopard installed, things that I’m interested in:-
* RSS reader in mail
* spaces
* calendar App showing todays date
Things they didn’t mention which i think are good:-
* Tabbed terminal windows! Apple+T for a new one, Apple+}|{ to move between tabs
Aside from that, the coverflow-esque viewer to finder is quite nice – and pretty quick too. Admittedly, zfs is there – but no zpool create yet 
Think i’ll have to get the developer kit for that one.
