You can't decide between an underpowered phone running on an ancient operating system and an overpowered phone running on the most powerful mobile OS to date? What's there to think about? 8525 - no doubt about it.
The 8525 is a marvel of computing. It is amazing, and the sliding keyboard makes you feel like you have a transformer in your pocket. It is much more powerful than the 680, and it is neater too. You will just get so much more use out of the more advanced model, even if you just stick to emails and web browsing, the thing is so nice to hold and use.
