As for getting experience - it is easy to gain it by cloning any current 
OS version to card ;-)

For previous devices it felt faster when booted from card except some 
corner cases (frequent fsyncs in sqlite causing metalayer-crawler to 
take ages). For N900 the boot feels a bit slower but once system is 
booted I don't see much difference (with ext2) but it is too early to 
really tell.

And BTW when OneNAND is free, in theory it could be used for swap (over 
ubi) causing less writes to eMMC when system is out of memory and 
already slow.
