Probably - look at the shot of the racing game; the speed and timing on the ClamBook display do not match those on the phone.
It's a nice idea and I could use it to replace most of my desktop functionality - but then I sometimes have to burn a few DVDs, run some in-house developed apps, read/write USB sticks and use a (USB) Yubikey (OTP generator) to access some of our systems so it would be very hard to switch 100% to a ClamBook, and there's no way I'd want to keep alternating between two sets of kit - kinda defeats the purpose - but some may be able to cope.
