Have to say I was indeed tempted when the E6 pro came about, but like SGA and another post here mentions, the impracticalities of a non removable battery swayed me away from it, irrespective of its good performance; it has to be practical in the field, and if you are using one daily, the question of getting a worn down battery replaced arises, this would entail a significant downtime, possibly weeks rather than days, an aspect that would both impact ones effectiveness and also the probable reselling value, unless it could be demonstrated that the battery replacement could be turned around here in the U.K.
No such issues with the Pulsar, so taken in the round, there's no contest.
