I'm even working on putting 2x 18650 LiIons there I wouldn't be afraid of obsoleting due to lack of batteries. Also, in case of always-from-AC scenario, it have some benefits, to keep a battery inside (one that you don't care about actual capacity after years of usage). It acts like a integrated UPS

Thanks a lot, but I'm just a small firefly here - look at our kernel hacking guys, half of hardware modifications wouldn't be possible without their work.
I used to have "external" digital compact camera - the problems is, that everytime I seen something worth photo'ing, I haven't had it with myself (murphy law), so I ended up doing shot with N900 anyway.
