I wouldnt recommend installing on a system that you can not afford to have reformatted but this version is quite complete as it includes 99% of the final release's features.

You can also download the Virtual PC images which saves you that headache of reformatting or using on a development only system.

Please feel free to post about any tips or new features. Also, note the version you are running. Ie: Standard, Pro, Team Suite etc.

Im downloading at 330 KB/Sec.

Enjoy.
