EEG is much easier to collect data from. Fmri needs a big machine and lots of helium, so it's impractical for daily use.

Perhaps it's more practical and better with temporal resolution, but it depends on how concerned you are with spatial resolution too (which EEG is quite poor with).

That's the point of this article. The experiment routes around the lack of good spatial resolution in the data. It's like a much more sophisticated, much less easy to game polygraph.
