I’ve been impressed with the N900 reviews and videos thus far and I would love to pull the trigger on my pre-order, but I have several critical questions… If I decide to go with a data only plan from T-Mobile, what disadvantages are there with only using Skype to make phone calls instead of a voice plan? Will incoming calls to my Skype phone number appear on the desktop just like an incoming call would on a voice plan? Will I have to perform an extra step in order to make calls that I wouldn’t otherwise? If I leave 3G coverage and only have edge speeds will I get poor voice quality or lose multi-tasking capabilities? (ie. Internet browser?) I realize that some of these question may not be answerable until the release of the N900 in October, but maybe some of you can share your experiences from using Skype on previous internet tablets. Thank you for your help!
