For my style of photography, the X1 as sold is incomplete. Compared to the M series, the X1 is a small camera and the handgrip does really help -- but I should add that I have always used a handgrip on my M6. An even more important accessory for the X1 is a viewfinder, which Leica sells at an overpriced $350 -- if you can find one! Solution is to get the 35mm viewfinder from Voigtlander which costs about $160 and does a very good job and it is available. I'm using the Voigtlander finder without any problems. Of course, I was one of the lucky one who has been able to obtain a X1.
