First couple of thoughts on the revue
I noticed the comment by Nick Heath that only microsoft apps would work with the new os. That sound rather early applish. They were so propriatory at that time that people didnt use apple in droves because they couldnt use anything but apple hardware and software. Now they are going to remove a lot of software from our use, again.
The other thought/comment is that i went and downloaded the 'beta' then saw the 'notice' that if you installed the beta, then chose to return to your origional os, that you would have to do a reinstall of the origional. There was no comment about running it as a second os you could choose. Be sure you want to install the beta only to find you have to reinstall your previous os and possibly all your associated programs
