Finally got around to updating the firmware and wish I had done so before my honeymoon. It seems fast and stable which is good.
Was using the 0.2.0 version whilst on honeymoon and had 3 crashes that needed resetting the device to fix. I lost all my bookmarks for the book I was reading too.
No idea why they happened as until then I had only had it crash once since installing it.
Cheers,
