I have the 9.7 IPP w/ Verizon LTE. When I'm on WiFi, I get serious lag. If I'm in the Settings, scrolling will jitter and then freeze for a bit. Then start working again. Same is true for other items; If I have the SmartKB plugged in, and do a CMD+TAB, it'll pause, then go. When I turn off WiFi and just use LTE, its fine. Could it be the WiFI radio? Anyone else experience this?
