The browser is a definite weak point. Vita browser loads pages slowly and it likes to reload pages if you have more than one open and you flip between them unless they are trivial. Also, won't load some larger pages at all. It has appearance as though it's not being given enough memory, even though Vita has more RAM than PS3 (not directly comparable since different instruction set architecture). After some update this year it even no longer remembers how far you have scrolled down when you manually reload a page, and is having trouble reacting to within-page jumps (e.g., for GAF it will no longer autoscroll to the particular post if you click on newest unread post). It also has some display issues with text, where often letters will not appear or are cut off - i.e., the letter ell can readily disappear entirely. The zoom function only works on some pages. Recently, it has had weird display issues with some graphical elements where they flicker and change size making whole page unreadable. The Vita browser crashes fairly often. PS3 browser is all around much better.
It's not a Vita. They have a chance to position it as a Roku competitor, but they are way behind. Even so, they are competing in that price range, and some people will get it instead of a Roku on the promise of future capability and because it can do some PS-related streaming. When they are marketing Sony's own music and video services they will be pushing PSVtv.
This is what everyone expected Sony to do. It should still be coming.
There's no easy way to sync. Vita is behind in all sorts of functionality and apps. We still don't even have crunchyroll (that might have been slowed by a negotiation issue). There is hope that PSVtv will lead Sony to strengthening media center capability and other apps.
While they are about it let's hope that they ditch the bubble interface and remove the 100-app cap. I expect only slow progress on these things, because I suspect they've painted themselves into a corner in some ways.
