Dear all,
now as the discussion has calmed down, let me try to draw a first summary.
Regarding the original question about Bluetooth or WiFi, there is a clear winner: WiFi (24:4).
That was much to my surprise - since I had expected that Bluetooth comes out better in a low-end device because it would offer more options to connect to external devices (GPS mouse for navigation, keyboard to better use PIM applications, mobile phone to sync with). But apparently, WiFi (i.e. full IP/Internet access) is more important (in a Linux PDA).
And funny enough, as we have run this discussion, I got the indication from the manufacturer, that they now even consider integrating both - so the result turns out to be of some academic importance.
The second discussion level was generally about the demand for a lower priced device. Here the discussion has puzzled me a lot, since on one hand I (think) I always read that the Sharp Zauruses are more expensive than anything else to reach broader use, but if I propose a less expensive device, it does not have enough functionality or is not extensible enough.
So, the only solution would be that we all use, promote and buy more Sharps so that they come into economies of scale and the price can go down to reach a level where Dell and others already are. So it is about strengthening and extending this community. What about a "proud Zaurus user" button on each of your home pages or a "Zaurus" sticker on your car?
Or is there really no demand for a lower priced Linux-PIM-only-PDA (with reduced functionality of course)?
Many thanks for discussing these topics,
Nikolaus
