Like the ui. The mobile app is nice. Works seamlessly on ubuntu with chrome extension. Have not seen a situation where I have ran out of cpu cycles. I have an i5. Its nice. I have faced one challenge though a few times, that is, it takes a little while to reconnect when u bring the laptop out of suspend. It connects eventually but u wait like for 15 seconds before u can start. It is not a deal breaker though :) good job. Keep going.
