So i got it (13 inch MBA) the other day, haven't stopped using it. Even for a bit of gaming it seems quite fast, so quite pleased with it

. Plus the screen looks a lot more sharp than I'm used to (guessing because each pixel is so small/closer to other pixels) - apart from one font used on sites (not sure what one) its a lot easier to read i think.
Is there any way to show all open windows in the dock though? a bit like in windows xp?
I often have lots of windows open (in xp i have the start menu task bar thing at two rows high because i have so many open normally) - in os x its impossible to keep track of where each one is. The nearest i've worked out is by minimising, it moves it to the dock. But once restored its not in the dock any more, so i quickly lose place of where it is.
Right clicking on the icon in the dock (eg the firefox icon to show a few FF windows i have open) isn't any where as easy as just finding it in xp would be.
Also, under settings - security, i encryped my home folder with the filevault thing. Does this encrypt everything? Like all my firefox data (i.e. passwords) - is that now encrypted?
oh and lastly, apart from steam, where can i get digital downloads for mac games? ive been trying to find some rts or sim games for download, but can't find any.
