Well, I don't think the comparison with n800 is fair, what we have here is not thumb, but thumb2. Which is a totally different beast. There is no performance hit because of ISA switching, as there is no ISA switching . BTW I thumb2 compiled microb, and the difference in code size is about 7-8 MiB, which is a HUGE difference, having in mind browserd is always running. Unfortunately I was unable to run that binary and didn't have time to check why it aborts. microb will be my next favourite for thumb2 compilation once what is done so far is proved to not bring problems

@don_falcone: yeah, will add such a warning once I am back home, the reason is that Qt libs (being much smaller) are moved to rootfs from /opt. Theory says we sholud have an additional performance gain for Qt applications if libs are on faster NAND (NOR or whatever )
