As you say, EEG is less accurate spatially and apparently the hopes are for far higher real-time resoloutions with MEG. The intended applications of MEG - as far as I can see from reading two papers on it - are in studying brain conditions rather than individual patients. It's a powerful research tool which may for the first time, for example, map the exact areas of the brain affected by various forms of dyslexia and autism.
