Seagate's 1-inch drive--small enough for cellphones yet?

Seagate has announced a new range of hard disk drives, including the pictured one-inch model, which will come in 2.5GB and 5GB versions. There's also a Type 1 CompactFlash-format version coming. Out in the third quarter of 2004, so they say. Could this finally be the drive that's small enough to make it into a cellphone? Questions of shock-proofing aside, it's got to happen sooner or later.
