Till, I have a question about the costs for submersion/initiation. The book lists the karma cost for initiation as 10 + Gradex3. Thus, the first rank is 13 karma, the second is 16, and so on. This price is listed both on the karma cost table for character advancement as well as in the section on Initiation in the Magic chapter.
Submersion isn't listed on the karma cost table, but the Technomancer section of the Matrix chapter lists the cost of Submersion as 10 x (Gradex3). So, 30 karma for the 1st grade, and 60 more for the second, and so on.
I feel...like this cannot be right. One of these costs is wrong.

The costs of magic versus technomancy is, in all other ways, roughly the same (4 karma per complex form as opposed to 5 karma per spell, but if anything technomancy is cheaper in that case...not more than twice as costly).
I'm going to check errata, but I wanted to run this by you for a ruling as well, just to be safe, so I know what I'm getting into here.
