Removing SD Card while Titan is on?

[TurboFool]

I think a general rule of thumb is if whatever it is is easily accessed from the outside of the phone, it's safe to remove it while it's running. If it weren't, they'd place it in the battery compartment, under the battery, like they do with SIM cards... unless you're Nokia and you're designing a game system and phone all in one and somehow believe gamers don't care about switching games very often.
