Most of the comments would suggest the software is still somewhat immature. Remember that this is the very first version of WebOS for the TV, and it has only been released for a few months now, and during that time several updates have been released that have resolved some issues. The good news with this is that LG have probably a few years worth of updates to solve these issues until the current hardware is obsolete and you HAVE to buy a whole new TV set. The bad news is of course that we have no idea what kind of items they have on their backlog. I doubt a company like LG have portals like Microsofts "Connect" where e.g. anyone can vote up new features, bugs etc for their products. For us, the only way are through official channels. And the more that report a specific problem, the more likely is that it will be resolved.
For a first release, I think the OS is "OK". There are many features missing or not working properly, but I assume (without knowing) that they will be resolved in due time. If not, then the next time I won't buy an LG TV...
