It is faster, but not by huge amounts. If I would've had to pay for the upgrade, it wouldn't have been worth it.
Battery life has certainly taken a toll and the device doesn't seem to run as solid as before - more force closes on the browser and weird non-connectivity problems (!).
As long as I reboot the device every day or so, it runs smoother, but what a pain.
Not really, in my opinion.
i've had mine since it launched 9.5 months ago, and obviously 4G is faster since I got nowhere near 18 down, 10 up on 3G. Battery life declining since the 4G upgrade should be no surprise at all, but I'm still getting 3 full days out of my XOOM, compared to the 4.5-5 before the upgrade. 3 full days is still great.
I personally still don't think the $200 is worth it when a contract is involved. The number off tablets coming out now and into early 2012 is ridiculous, and prices will have nowhere to go but down.
