I like the feature of the remote so that I can capture solo mission lock off shots with ease, but goPro seems to have superior mounting systems at this time.
The wifi/remote is the only thing that could been seen as an upgrade over the goPro HD 2. The profile is different, though not necessarily better. Sony also has the mini SD card slot, but for me that sucks cause I have a few standard SD cards I'd like to keep using. Not to mention my computer has a built in SD card reader.
So at this time, I still like the goPro HD 2.
