I re-updated my Kobo by instlaling 1.9.17 first, then updating to 2.0. This did not resolve the sluggish page turn on epubs. However, it did restore the missing fonts. The 2.0 update is missing the Delima, Felbridge and Times New Roman fonts. If you want your kobo to have all it's font's intact (important since apparently user installed fonts aren't working correctly with Epub,) then you must first update to 1.9.17 before updaing to 2.0.
For those who havent' done this before, you can download the previous update here:

Unzip the contents of the zip fle and copy them into the .kobo directory on Kobo.
Wake me up when the first patch hits, but overall, I like the direction of this update. Kobo is almost viable again.
