I am impressed what your component can achieve!
I created an application for Win CE 6.0 using IE6. It used a LOT of memory (about 17MiB) and more importantly it leaked memory a lot.
I wonder how your component will compare and if there are any known memory leaks?
I've tested the browse sample app on the device and its consuming 1.3MiB which is quite good!
Do you have any number regarding memory consumption on the mobile device?
