The scene I tested this on was mostly static so the H.264 codec should have yields smaller files, like Tom's 7000kbps, but no. However, I do notice darker scenes yield smaller files. Therefore, I've never had to use a larger card than 4GB. And the 4GB card I use is only Class 2. I tried a 16GB Class 10 card in it and the difference in scenes with motion under even very marginal lighting conditions cannot be easily detected.
I've gotten more than two 20 min. clips on mine before the battery craps out. Both full clips were exactly 20 min. to the second. Battery capacity or charge state seems to vary on these little cams quite a bit. With the external battery now available, recording times can be very long (e.g. 5-6 hours).
