It´s true that depending on how many programs you run (email checking, IM-protocols connecting, Real windowses open) it might get laggy. And also there is some apps than basically are not on level of smoothness what iPhone delivers.

Could someone please tell me what is this video call outside Skype. I have never ever used it but some people have been talking about it. Isn't it something that is dependend on your service provider or what is this thing and what protocols it uses and what phoens have it. I have never ever seen or used it besides skype and gtalk.

It lacks tons of functionality on Phone apps and PIM, but then again it´s all about browsing, messaging (except email), music & video. Only hope is that there will be commercial apps that provide phone functions what people are missing.

Then again if yout try to use it same way as your old phones you have probably bought wrong device.
