Windows 7 Beta

I am a OS X user but I am curious to see what people think about the new Windows 7 OS. From what I have heard so far it is a vast improvement over Vista and so many people started downloading after it was announced that Microsoft had to suspend the downloads to get everything working again on their servers. If you want it and have not gotten it yet you should be able to download your copy over at Microsoft. I hear it comes with a huge warning message so read carefully. If you have been using it let us know what you like and don't like in the comments below.
