So it seems that SurfaceRT apps are only NGENed after about 24 hours -- that might explain why several reviewers complained about slow app startups while users who bought them don't seem to have that complaint.

So, if you're going to blog about how terrible the Surface is, remember to run the app for a minute or two and keep using it for a couple of days first Tongue Out
