Passed 117-102 today! The printout says that I only missed 1 question out of 60! Which is partly luck since I know for a FACT that I guessed on at least 4. Luckily, since 20 of them are seed questions it appears 3 or more of my incorrect answers weren't counted.
I found 102 to be a lot easier than 101. It's like this, if you work with Linux for a couple years then you are going to be intimately familiar with the objectives covered in 102. Whereas with 101 even if you work with Linux all day you are STILL going to need to study and memorize superfluous command options.
I think LPI did a good job of weighting objectives based on real world use. X, printing, etc are required topics but not necessarily heavily used day-to-day by most admins. So they are weighted appropriately and seen less frequently throughout the exam.
I used the Sybex book and once finished reviewed with the Jang "in depth" book. I took notes as I went along of any commands or concepts that were new to me. I then went over the 102 objectives on their site and verified that I had been exposed to all the "key knowledge areas", refreshing on ones I wasn't entirely familiar with. I think that both books do a pretty good job covering the required material. If you are familiar with the concepts you may wish to save some time and focus more on the Jang "in depth" book since it's - uh hum - less in depth.
On to LPIC-2! Looking briefly at the objectives I don't think I'm going to get by on previously acquired knowledge.

It's not everyday that I have to recompile the kernel, patch and rebuild modules, screw around with udev rules, modify bind zones (by hand)!

Should be a great learning experience!
