I have the 5741, not the 'G' model, not sure what the difference is but the only problems I have are slight. The system (Windows notification) sounds are intermittent, sometimes they work, sometimes not. It isn't drivers as DVD sound playback is fine and they play fine with ear phones connected, I believe it's more to do with the signal to the speakers causing the problem.
Another small gripe is the touch pad, it can be a little unresponsive, especially the extra features like scroll and the touch areas like corners that can be set to move forward or back in IE.
The viewing angle on the screen is a little narrow compared to other displays now days, it's not that you can't view the picture from an acute angle, you can, it just looks better when looking square on.
Other than that I don't have much to complain about, for the price, it's a great little notebook and surprisingly light too.
