My take to refute the "Pefromace gate" Added lag video
My take on the Surface RT peformance issues
Microsoft Surface Performance I (via Abraham Saenz)
Microsoft Surface Performance 2 (via Abraham Saenz)
Second video coming soon where I intentionally cause some lag.
Honestly, I think the performance issues some people see are caused by applications not closing its state correctly or soon enough, Microsoft seems to have favored faster resume times for apps running in the background and that may cause some apps to take longer than normal to get suspended thus, causing "lag"
