I don't want to accuse old nick of working for sony, I mean I'm a sony whore myself, but the above writeup sounds a hell of a lot like a press release. The CMD Z5 certainly has some limitations:

    The games suck.
    No doubt about it. Fishing or Shooting, either of which is slow, repetitive, and makes poor use of the jog dial.

    The interface is poorly designed
    Ok, it's not awful, but there are little annoying gremlins, like the pressing the jogdial three times in a row to confirm sending and SMS, or the way a back-press on the jog dial can mean, help, clear, or cut & paste depending on the context.

    You can't use it with one hand
    Well, I can't! The instructions say I should be able to, but I either have to repeatedly shift my grip by pressing it against my body, or try to do everything with the jogdial.

    Sony customer support is a heap of steaming dung
    Supposedly there is an upgrade available to fix an echo problem with the CMD Z5, but considering the the crap that I have already put up with, the echo isn't that bad.

The jogdial is cool though, you can press it in, pull it backwards or push it forwards, making it something like a joystick that is analogue in the vertical axis. I just wish it had been positioned a bit better, and that the software used it consistantly.

Oh yeah, it is sexy.

But sony customer support really REALLY sucks.
