Which has the higher demand? There are more people with series 40 phones, but the people with series 60 have more money to spend...

Which has the higher supply? People have been doing MIDP 1 longer, but more developers will be wanting to use MIDP 2 now...

So (particularly for J2ME games, but general knowledge is welcome too) which is the harder environment to sell to customers and publishers - series 40 or series 60, and is there a big difference?

Thanks,

Mike.
