Finally, they dared to ask...
We (the customer) want mobility in our solution on any kind of a device..., mobile device that is...
iPhone, iPad, Windows mobile phone, Android, regular PDA... (with limited/essential data only)

We already have an AJAX app, that does most of it, but the screens are to big for the current phones, we need to revise that any way... But that is i.m.o. not the direction to go for.
There is one slight advantage, it are just enquiry programs they (currently) want.

Currently we have already a rather complete solution, with PDA (Motorola Symbol 90xx series) with a dot n e t app on it, but that app is written to use the scanning possibilities of that particular PDA.

And here comes the drill...
What environment (device/os independent) can have the largest install base that is compatible with all/most devices...
Any thoughts are more than welcome.
-thanks in advance-
