Read about 1/3 of it and just stopped. I knew this stuff from hands on experience.
Used Transcenders as well, although those honestly weren't as representative as they usually are of what the exam is like.
Next up? *shrug* Dunno yet. Tempted to leverage this 85% off thing for elearning to learn SCOM, SQL2008, or something like that, but I really should be focusing more on storage and VMware. I'm also still learning about PowerShell and what not, too. I'll figure it out soon...
