Are you getting the Wifi only model, the 3G model, none at all, or are you not sure yet?

If there's some way to use 3G to telephone with Vita, the question is obsolete, definitely the 3G model.
Else, I want to see the advantages 3G offers me first.

Too soon to tell. Need to know more about what the 3G does and how much it costs per month.

This... but I intend to get one or the other.

i have a phone with a free 3g sim card, which can act lie a wifi hotspot so im fine using the wifi only. i guess its sim locked to at&t or aquivalent in other countries and so its no use for me to get a second card.

yeah skype will be available and web browser will allow us to make calls

will depend on 3G plans,if unlimited plans are available then 3G

SONY please allow third parties to develop apps that way i can use it as my primary device

I'm leaning towards the Wifi one now, but it might change depending on the benifits of the 3G one.

You sure Sony can offer Skype on the Vita? MS bought a few weeks ago. They don't have a handheld, so they don't need to compete with Sony here, but still...

this. depends on how costly per month, and how valuable that service is. (Browsing? Gaming? Phone?)

I'm curious what the break down in sales will be for each model when all the speculation is gone and there starts being real sales.
