1) When you hear very quiet radio via WLAN, no creaks the device, although noisy, but annoying. I am curious if this will really solved soon with a software update.
2) The display is not dimmable and personally me in the bedroom even when power is off when the display is slightly darker, nor too light.
Without these two flaws I had assigned full 5 stars.
Addendum, Stand 11.03.2011: With the latest update, the crackling is gone and point 1) my criticism obsolete.
