I'm just upgrade my Windows Vista Ultimate to Windows 7 Ultimate yesterday. It looks pretty nice. The boot screen was changed with the flying Windows logo.
I like the Windows 7's taskbar. It is very convenient to use. The visual effect also nice. It tab the windows smooth and fast.I found that my touch screen can't functioning as well without the stylus pen. I just can touch the screen with with the pen only. So disappointed I can't test the multi-touch technology. And also the Kaspersky Internet Security haven't support Windows 7 yet, but the Kaspersky released the technical preview of KAV for Windows 7.
