Well, I've been goingdown a bit through the lifestyle creation rules that appear in SSG and truth is I found that they should be more or less directly convertible for SR4. Afterall, the lifestyle costs have remained almost the same. Obviously, some edges, flaws and maybe even a couple attributes (like the one that handles how strong is your Matrix access) might have no use now, and others might need a bit of converting, but it seemed like something that could be used until something similar appears for SR4 (which will take time, probably).

Well, the question is, has anybody tried anything similar? How did it go?

The system is pretty much compatible. Personally, I see no reason at all to change the Matrix part. After all, wired or wireless, you still gotta pay someone for legal and/or illegal access. Higher comforts in Matrix could mean that your connection is pretty solid, especially when at home, and posibly include bonuses or penalties to Signal.
