Samsung Focus S: Lag? FFC App?

I picked up a Samsung Focus S on Sunday, my previous phone is a Samsung Focus. The screen is gorgeous, one of the best panels I've looked at. The gpu makes scrolling and games run smoother, and overall I'm happy with the battery life etc.The camera.....I'm still adjusting to it, seeing how it works best, but so far I'm not seeing dramatic improvement over the fantastic camera on the original Focus. Again, I haven't had too much time to test it and play around with the various settings. But I have two glaring problems:

1. Lag: specifically on the keyboard. It's unbelievable, the keys are always way behind where I'm actually typing, which is really disorienting. Anyone else experience this?

2. What am I supposed to use the Front Facing Camera with? There are no apps that I can find to utilize the FFC for video calls, which is the only good reason to want a FFC.

What do you guys think? I'd love to hear from other Focus S owners.
