My advice is to install VirtualBox and install the Windows 8 Consumer Preview 32 bit as a virtual machine. Set the VM to have 2 GB (2048 MB) of RAM (assuming your desktop has 6 GB of RAM or more). Maximise the VM to full screen and try it out, this will give you a feel for Windows 8 new interface to see if you like it.
I have purchased a new Inspiron 660S PC recently and konw that I am eligible for the Win 8 upgrade. I need top know the following before I can decide to proceed later on: 1. Under thw Win 8 Upgrade section of this website, the following was posted: •Please note that certain features of Windows 8 may not be available when a existing Windows®7 system is upgraded. Driver updates may also be required. Do yopu mean that the Upgraded Win 8 Pro version is not the same as Win 8 Pro Purchase from the store, i.e. Win 8 purchase from the store will have the full features?  What are the features are not avaulable, are these features very important for best Window experiece?   2. Drivers Update may also required My Win 7 drivers is now up todate, do you mean that, all the Win 7 Dell Drivers are no more aplicable to Win 8 and there are new Win 8 drivers for the same Dell PC ?  The user need to dowmload and install it again? 3 Existing software installed in the PC My PC came without Recovery disk for Win 7, MS Office 2010 Home & Student Edition, Mc A fee Internet Security 15 months I noticed that all the Dell Software and Mac Macafee Internet Security can be downloaded from the Dell Website Except Win 7 am MS Office. Do you mean that If i am not purchasing the MS Office 2010 DVD kit from dell , there is no where for me to install back the this program?   4. Reinstall back the Win 7 after Upgrade Let say I have purchased the Win 7 Recovery DVD from Dell, can I reinstall back to Win 7 if I find that Win 8 is not I want? Appreciate if somebody could assist me on my questions above.   Thank you
