I have just got the real Enterprise (we are under Software Assurance) version, and have upgraded my not very old pc to windows 8 now... been using it for about a week, and to be honest I am very pleased with the changes.
The start menu is a non issue actually, since the only time I use it in windows 7 is to search for something, like a program or a document/mail etc. What I get with the metro start menu is just a bigger result pane, so to speak, which is really not bad at all.
It took me exactly 20 minutes to upgrade the machine, which is really bloody fast (i7 with Intel 320 SSD/8GB Ram) and the only 2 programs it ordered me to remove before it was able to upgrade was MSE (weird, but seems to be build into win8) and Total Commander (works fine after install).
The things I like better than before would be, better jumplist control, and the file explorer is better, both in regards to view-ability and customization. Also the pc is overall definitely not slower, rather the opposite.. and lastly reboots are bloody fast (12-18 seconds).
Would like to hear from someone who have been testing storage spaces, it sounds interesting enough for personal use.
So overall my experience is great, so far
