ramblings in another thread. i think the beam shape is solved, its more what is the best for the price. the reason why i want to switch to the pure, is if i do some credit card touring, one less charger to have to carry as you just USB charge it off your laptop. i also don't agree with peter white's claim that the ixon or ixon iq handles perfect in rain. occasionally, it randomly shuts off in rain storms. a little rattle usually fixes it.
the battery life on the ixon iq is amazing. i don't even think about charging it anymore. i just charge it every once in a while out of paranoia that i haven't charged it enough lately
i am thinking about changing brake systems eventually, but i really wonder if having something that is mroe reliable or enclosed, but that takes a little more effort to repair or uses slightly less commonly available parts, will save me any time when it comes to repairs and replacements (i use bike shops to do this stuff because i am too lazy to learn how to do it on my own). i feel like you are trading a quick repair more frequently for a longer repair less frequently.
