Let me start with why only "almost" totally delighted. In common with so many (most?)other computer screens, the screen on this notebook is far too reflective. That is the only downside I have found but I do not know of a better alternative notebook at this price and performance. All other aspects of this notebook I rate 5 star and I am otherwise delighted and it is a real pleasure to use. By comparison my daughter's Samsung netbook has a really good screen clear of almost all reflections, but a netbook is too small and insufficiently powerful for my requirements.
I am pleased to find that the HDD is in fact 640GB, battery life after a number of cycles is dependably 3 - 4 hours subject to type of use, which I think is good considering the performance and screen size, the webcam is adequate but the internal microphone seems to garble (fine using external microphone). Internal speakers are adequate for most purposes, and the keyboard and mouse pad are good for a notebook. I use only wired connections so cannot comment on wireless operation but a large number of local home networks are shown to be available at usable and good signal strengths. I have upgraded the office software to Pro and this is handled easily and reliably.
For long periods of use I connect a Microsoft Natural Ergonomic Keyboard 4000 which I rate very highly, and a Microsoft Notebook Optical Mouse 3000 as I do not like any built in pointer devices, and this particular mouse has a very useful magnification button (particularly helpful with the above screen reflection issue!). I also connect external speakers for any occasion when I want high quality sound, and of course it can be used with a larger extenal display/projector. With these options this notebook is sufficiently powerful and versatile to cover most general requirements including professional presentations.
Overall, I love it, am very pleased I chose this model, and highly recommend this notebook.
