HT1202 One Device Synced to different info on two computers???

Question

My music library is on my PC. My apps, contacts and calendar are on my work laptop. My ipad is synced to my work laptop. I want to add all of my music to my ipad. I connected my ipad to PC, made sure everything I don't want to sync is unchecked, and then checked my music library, but when I went to sync it warned me that anything on my ipad not from the PC will be erased.
If everything but my music is unchecked, will it still erase my contacts, calendar, etc?  Or will the set up I described above allow my ipad to keep all the stuff from my laptop and just add my music from my PC.
If the former, is there a way to do what I want?  (I don't want to put my music library on my laptop.) Also, I have a bunch of songs in my music library that I burned, so using the cloud isn't a good solution.
Thanks!!

According to the article, you can drag playlists onto the device as well. I copied this from the end of the first article.
When in manual mode, to add songs or playlists, drag them from iTunes to the device icon in the sidebar. To remove songs or playlists, select them on the device in iTunes and press the delete key. You can also create playlists directly on the device.
I have never done this myself but I am basing my answer on the reading from various kb articles and just putting 2 and 2 together, so to speak.
When you go to sync content with the other computer, you have to set that to manually manage songs and videos as well so that it does not unsync the music that you already have on the iPad. If you uncheck Sync Music with the actual syncing computer, that will erase the music on the iPad. If you check Manually Manage, then the music should not sync and it should be left alone. At least that is the way that I understand it to work.
There is another kb article with some more information in it that is linked from the first article. This article is very recent.

I would try it this way. Sync and backup your iPad with your normal syncing computer and then add the music manually from the other computer. When you go to sync again with the normal syncing computer, you shoud get an alert if iTunes wants to replace any content on the iPad so you can always cancel the sync if needed. The bottom line is that as long as you backup and sync with the syncing computer like you have been doing, you aren't in danger of losing anything.
Make sure that both computers are set to manually manage music.
