for newbies, i recommend using the default sharprom. if you follow my links in my sig, you can change the look. then install meanie?s xqt installer which will run debian, openoffice. I recommend you buy wifi and bluetooth that works for the z. hardware compatability is a rere thing for the z. also buy the poweradaptor and do not use the japannesse one. buy the one that comes with the sl5500
which is the EA-70S.
after you learn the sharprom ropes, you can try other roms. the other roms are currently being developed. they are almost done and you can try these when you are brave enough.
