I just received my SH100 today, so I won't try to do a full in-depth review. However, in the hours that I've played with it I can already tell that there are quite a few 'quirks' that seriously hinder an otherwise great camera.
First, the camera comes with a touchscreen interface for most of the functions. Sadly, it also comes with a stylus which, in my experience, isn't optional to use in many situations (such as typing) - at least with my large fingers. Even worse - there isn't a place to store the stylus within the camera itself. Instead, it clips and hangs awkwardly from the lanyard. While a generally small nuisance (and perhaps a non-issue for those with smaller fingers), it would have been much nicer if the screen was sensitive enough to work via touch or there were discreet navigation buttons.
The biggest issue for me, however, has to be the software running on the camera. The UI isn't very pretty and is awkwardly organized. It feels very hastily thrown together. Again, this is a minor disappointment, but something that should have been easy to fix. Unfortunately, that isn't all. The software is also quite buggy! I had found several issues within the first few minutes (where was the QC?!) which took hours to resolve. For one thing, logging in to Picasa was a real pain as there were issues with the software recognizing both my email address AND password. The login for Picasa should be the same as my Google login. However, my account is associated with several email addresses and only one of them was accepted for some reason (and it wasn't my normal gmail.com account, it was a tertiary address I rarely use). Even worse - there's a serious bug in the password handling that prevents it from recognizing a password with any special characters! As best I can tell, only numbers and letters will work as they should. If you enter a password with a special character the password will not be accepted. This was a real problem for me as I did not want to change my password (I use many different Google services across many devices, and changing the login credentials on all of them would be a real headache!) Fortunately, I discovered an undocumented workaround/hack. If you change special characters to URL encoding (so pa$$word becomes pa%24%24word) it will work (even though it really shouldn't!) Unfortunately, this seems to prevent the password from being stored properly (only characters up to the first % are stored!). So far I have only tried logging in to the Picasa service, but I suspect these issues are present in all password fields and may well extend to user names, etc.
To be fair, the camera has some really great features and it takes very nice pictures for the price. In fact, it really could be an AMAZING camera if they ever get the software straightened out. Unfortunately, until new firmware is released, this camera has fallen fairly short of its potential.
