I used the MGH handbook as a medical student and during my two months as a resident on the Neurology service there. Keep in mind that I'm not a Neurology resident, so I'm sure they could provide better recommendations. The handbook certainly isn't meant to be a comprehensive review book, but is nice because it fits in your pocket. Several HMS students that took call with me found the handbook coupled with UptoDate as adequate for the rotation. The ones who were interested in doing Neurology wound up buying a copy for themselves in addition to purchasing some Neurology textbooks.
For my neurology rotation I used Clinical Neurology (part of Lange Medical Book) by Aminoff. The "textbook" is very readable and provides a good overview of neurology. For new advances in neurology, of course you can consult UpToDate or search for articles on Medline.
I agree that the Lange is a pretty good book but a long read.
Some of the medical students on my service have been using "Blueprints in Neurology." This book was not available back when I was a medical student doing neurology (2001), but I really liked the Blueprints series for ObGyn, Med, and Peds.
