You Can't Game and Browse At the Same Time on Vita

Not at first, anyway
You're playing on your Vita, but you want to hit the web to look something up. Unfortunately the machine won't be able to run a game and browser simultaneously — not at first, anyway.
Andriasang reports that if you want to use the browser you'll need to save your game and quit, unlike the Nintendo 3DS which allows you to suspend your game and use the browser. However, Sony has said this will be the situation "initially", leading us to hope it'll change with a future firmware update.
