Oh yeah, does it ever! Globalstar's form factor is better than Iridium's but the coverage isn't as good. We have two iridium units for forays into 'interesting' parts of the world (most recently the African Okavango Delta) and eight Globalstar units for disaster recovery efforts... it's just a pity G* doesn't have coverage in many of the very places one would need a satphone! I do find it amusing that Iraq is a "local" call, though.
