dos1 in his first post in this topic mentioned that with higher volume it is possible to upgrade the specs of the phone to OMAP4.
I guess it might be a good idea to start a similar poll to the one in this thread asking how much are people willing to pay for OMAP4 version.
The question may be like (assuming OMAP4 is a 4460):
How much would you be willing to pay for a Neo900 (complete device) with OMAP4460 dual core 1.2-1.5 GHz/1GM-RAM/1GB (instead of TI DM3730 version)?

If you add this poll, it can be referred in neo900.org
