We're selecting a processor for a new QNX based product and would like to hear feedback, pro and con, from anyone who 
has used the i.MX31 on a product.

Our last product used the pxa270 and it's virtual MMU and excruciatingly slow floating point (even though there wasn't 
very much of it) caused us all sorts of problems. 

The i.MX31 vfp and hardware MMU look good but we're interested in hearing about any gotchas that have been discovered in
 the real world.

Thanks for any and all info.
