There are a lot of HAC lovers here!
I personally do not find the shorter handles to be an inconvenience, but I normally carry *any* H bag in my hand as opposed to on my arm anyway, so that might be why.
I definitely don't think it's harder to find things in a HAC, if anything it is slightly easier for me because there's less "floor" area in a 32cm HAC for example than in a 35cm Birkin. I am also a new convert to the Chameleon bag insert, which makes that sort of a non-issue, as well, since everything stays where I put it.
I also like the slightly taller silhouette of a HAC in general; it's just very elegant to me and I find that it's a little easier to make it look dressier than a "regular" Birkin.
