No problems for me but the sound quality is very poor and also intermittent. The UI is not as good as the PC version, but I guess it is enough for now. I've been a long time user of Skype on laptops and desktops with no issues, wired or WiFi. A great system from my experience. I could really use it on the N800 in WiFi hotspots (where I have to fire up my laptop), but only if the the quality is good enough.
