It is an interesting idea... I assume you will offer downloads and software? I wouldn't think it a good idea for a news site or something.. LOL

The background image is very crisp and striking and the draggable desktop does make it feel like a desktop -- albeit one that is much neater than my cluttered workspace.

I would be concerned about what Microsoft will say about the Vista-like interface you have created... They have so many copyrights you would surely be infringing on one.

It would also be a disaster from an accessibility point of view as well.. It may be a desktop from a cosmetic standpoint but has none of the accessible options as found in modern operating systems.

With such a small amount of hard-coded HTML, I would sereously recommend you correct the 7 errors that you have.

On the whole, I like it - it is very neat and clean (as it stands) with a novel concept but depending on your audience and offerings may fall short in quite a few areas.

Have you considered a more conventional alterative alongside this theme?
