Have you ever tried to run Minimo on a Dell Axim X50v? At best the browser pops up a cryptic error message, at worst nothing at all happens. Project leader Doug Turner tracked down the problem to the particular address space layout of the X50v:

The core of the problem is that on this device we run out of address space for some reason. Minimo (including support libraries) today is a bit over 10mb of code, data, text... The way I understand this failure is that executables and dll's load after (below) the last XIP ROM-based DLL. On the Dell Axim, the lowest such dll is apicore.dll which loads at 0x009d0000. This is about 9.8mb of address space. On the Imate Jam, this same library which is also lowest loads at 0x00F3000. This is about 15.19 mb of address space. So, clearly we can't load anything bigger then 9.8mb on the Dell.
