glossy screen looks better under controlled lighting (ie in my studio) and matt looks better under difficult conditions (ie outside).
I’d think it not wothwhile to pay extra for the matt screen, anywhere you’d need it, you’d probably want some kind of shade over your equipment anyways.
recording to hd only saves time when editing, rather than shoot, import, edit it goes shoot, edit. i use imovie or quicktime pro to record to hd.
