today i got my P2A. it differs from the P1A in many details and seems to be an improved version of the P2A. now i am wondering if the P1A was improved too. say hi if you acquired a P1A most recently (what's your serial number) and if your copy has square threads too similar to my P2A unit.
anyway. wtf cares. most of us have already bought the P1A, P2A or both. so comparing older versions with the improved versions is in vain or makes no real sense. with my (improved version of the) P2A i have lost all (potential or possible) lego-ability .. on the other hand i could regard it as "really different light" since so much is different (or "improved"):
knurling
head (driver disc, ..)
tail (aluminum design/machining)
switch (design, clicky, assembly, rubber boot cover)
tint (greenish now!)
threads (square-cut now!)
what else
