Sorry, a DROID. Good to hear it's working out for you. To gain control over the device to the extent that you can on the N900 (closed bits not withstanding) you must root the device. This usually involves finding an exploit, which will likely be patched later. This is true for all Android devices save those sold by Google directly. Well, "tivoization" describes Motorola's bent with every non-DROID phone they've released. TrustZone checking signed bootloaders checking signed kernels which check signed filesystems. Even with the difficulties that are present with the N900, it's nowhere near tivoized. And IIRC, in ignoring community concerns I hardly think Nokia is alone (I don't recall Android implementing any sort of open governance, for better or worse.)
