With that said, would having both a Pyra and Neo900 be redundant?
Do you carry your phone in a bag (if you carry bags, that is)?
Do you feel comfortable pulling out something resembling a 3DS to do office work on-the-move or even to text friends?
There's also a major caveat to using the Pyra as a companion device that's rather unique to the Pyra- its features and how many of them are useful on-the-move. While having heaps of features is usually a good thing, a significant chunk of those features won't enhance your portable computing, thus making the user the primary bottleneck as to what features are used on-the-move.
Idk about you, but I haven't seen many people carrying around hard drives with their eSATA cables in tow just to piss off iPhone users.
While it's not uncommon to carry a USB stick with you, I don't know of anyone who carries two of them.
Also, having speakers on a handheld that don't totally s_it the bed isn't bad, but why not carry some headphones for a bit of privacy (and courtesy)? Don't want to carry headphones or a headset? Then how do you expect to make use of the 3G modem for a quick chat with your friend?
For the Pyra, there's already talk about the 1st hardware upgrade in the distant future to an AMD-based SoC, which means MUCH better open-source graphics support than PowerVR. However, that's far from materializing right now.
