Yea I was shocked how good things looked in HD (Comparing to using xbmc for a couple years on some crap 30/40 inch regular tv)...
Hence why I created this poll to see how many people were in my shoes, not knowing how HD looks! Suprised with the results though, there's a big portion who have never seen xbmc in HD, I'm sure there are a lot more then that too, that have paid to get their boxes modded, without knowing you can set it in HD...
Anyway, not sure about the 128mb of ram thing, I always thought it doesn't matter, could be wrong
