who knows, Sony will later on reduce 3G to posting tweets.
Reason?
Consumers complaining web surfing with 3G sucks up too much bandwidth.

consumers then complain too hard to type on vita. what will Sony do then?

true. Mgsrulz already pointed that out. but the problem is Sony won't allow online gaming using 3G on PS Vita. Even if you get the 3G version, you will need to use Wifi for gaming. 3G is only for browsing, messaging, Skype, etc. they stated "3G won't have enough bandwidth" as the reason. so better get the Wifi version, unless Sony planning to enable 3G gaming on future firmware, no?

Sony Denies Reports of Full Remote Play Compatibility for PS Vita

There were some reports a couple of weeks back indicating that Sony would be releasing an update of some form that would make all PlayStation 3 games playable on PlayStation Vita via Remote Play. Sony officials have denied those reports.

Freelance journalist Munechika Nishida conducted an interview with Sony's PlayStation Vita development staff for the latest installment of his "Random Tracking" series at Impress Watch. He asked Sony Computer Entertainment Senior VP Yoshio Matsumoto and Division 2 Software Development Head Muneki Shimada about the reports.

"That information is mistaken," said Matsumoto. "The compatibility is achieved on the side of the PS3 game, just like normal." Shimada agreed, saying that as with previous implementations of Remote Play, games will need API support.

This appears to mean no catch-me-all solution for making all PS3 games playable remotely on Vita.

While Sony demonstrated Killzone 3's Remote Play support at the Tokyo Game Show in September, it has not said when Vita owners will get to try out Remote Play for themselves in games.

The memory storage for the PS Vita is really expensive. I wasn't that disappointing with the low battery life. But expensive memory (32 GB for USD 120, which almost half the price of the wifi model of PS Vita) is kinda irritating.

wait for sandisk lo.

But can other brand memory card be used for the PS Vita? I believed the the memory card(MMC) that Sony is selling is a proprietary format...

So by theory, we can play PS3 games in our PSV via remote play aka transfarring in MGS games?

So, how does this works anyway? Do i leave my PS3 turned ON for whole day while I go to somewhere else, and play any game from my PSV irregardless of any location?
