I think you will have to be way more descriptive. What, specifically, are the problems you would like to discuss? I have not done much work for Palm devices, but I at least made some attempts - had the SDK and all set up. To me it's always been infinitely easier to make Maemo applications.
As you mention power and memory - are you maybe talking about problems with running applications? This again sounds strange to me, if you compare with Palm devices (2KB-12KB heap sizes..).

So, you'll just have to be a bit more specific or it'll be very difficult to comment.
