Depends if you're a gamer or want a device with a decent browser.
The Vita has much better games of course, but the browser is limited in function, though competent if all you want to do is browse a few sites. If you'll be spending your time on Face Book or things like that, you'll be better off with a tablet.

The PS Vita was designed to work with the PS3 and you should own both. The PS Vita is a portable with less power and capabilities than a PS3
No you miss the point it is a portable and you are to have a PS3 and the PS Vita . The PS Vita is a Portable Playstation that works with the PS3 and you will find they are both better when you have both. Either separate is not as good as having both. The PS Vita is to be compared to the PSP or Playstation Portable and it is better than a PSP. The PS Vita can not take the Place of a PS3 console and it never tries to do so, it was designed to replace and improve on the PSP with a better more advanced portable game player. Well, PS3 slim looks cool and has more games than PS Vita, but the PS Vita will have graphics that look similar to the PS3's but probably SONY will come up with some other games for PS Vita and one bad part about PS Vita is that its not cheap, but also maybe SONY will lower the price by March or April or May or maybe next year but i'd say PS Vita because its most likely a portable PS3.
If you have the money and really want to get the PS Vita then you should treat yourself to one.
You might build a PS Vita PS3 system, but you can not make a PS Vita. You are not even going to be able to purchase the parts to make a PS Vita. You will find that it is much cheaper to purchase the Playstation Vita than to try building one.
