I read and article talking about moving beyond 960px width for websites. This width is considered optimal since it is divisable by 3, 4, 5, 6, 8, 10, 12, 15, and 16 (no these aren't the Lost Numbers ;-) ) This helps in grid placement and this really doesn't apply to Silverlight apps but I started to wonder what would be optimal.
What would you recommend as the optimal resolution for a Silverlight app?
I'm thinking 960 x 720 would be in the range of almost every monitor out there.
Or maybe the next step down 720 x 540?
Personally, for the type of apps I do, I wouldn't bother to try and support people with less than 960px of available space. There is always going to be somebody with outdated tech/monitor size...and 960 is probably going to cover 95% or more of any target audience for me.
