I'll rephrase that to minimal "problem". It's just the usual lag that accompanies Android devices. Not a deal breaker by any stretch of the imagination though. Awesome screen, ridiculously good battery life (got almost 2 days, with light to moderate use, you can easily get a day minimum regardless of your use), hd movies play back wonderfully, and as mentioned ICS is going to make it much better and that's coming on the 12th. For those interested in hacking and ROMing and theming the bootloader unlock tool is coming too. Really can't recommend the tablet enough.
