I tried all the vertical cams, incl the PC105 which I believe has the same form factor as the PC115. The vertical cams in general feel awkward to hold. Worse, the PC105's zoom control is *HORRIBLE* not only because it's so small but because it's very tough to reach. The Canon Elura 300 was better, but in the end I got a Sony HC40. It is ergonomically wonderful, easy to use, and has close to (though measurable less than) the same low-light performance as the stellar TRV22.
