Expresscard/34 slot -- best usage ideas?
I know it can be used for various different connections to the MBP, but what connections are they, which are any good, are they powered, and what rough price is each option?
Are there any unconventional (weird/funny) types of thing some people have used these for (like USB has fans, lava lamps, or whatever pretty useless idea someone came up with for them!).
Also are these things hot-swapable, or screwed in type things?
As I said, I'm pretty ignorant on this thing, so any knowledge greatfully rec'd 🙂
