Really, guys, you should all have a dual-boot Win 10 partition and use it as much as possible, so that you can send your feedback, if nothing else... be feedback the change you want to see.
Nah, I'll let you work for Microsoft for free by your own. W7 works perfectly "fine" and I'm in no hurry.
And I'll leave it to you to ***** and whine about how MS just can't seem to get the OS right no matter what.
I'm not saying to go out and buy it, I'm saying, give them some feedback while they are still in the process of deciding exactly how this OS will behave and present itself to the user. Not necessarily bug-reports, if you don't feel comfortable "working" for MS (I think I've submitted a total of... 0 of those so far; this thing just works as far as I've seen). I'm talking about irritations with the OS. Give them a piece of your mind. If they don't get it right, well, toss the partition and be done with it. Win-win. Right?
For the record, XP works just dandy as well... 
XP works "dandy"? I still remember the shudders of having a XP disk, install a pc with it, go to the microsoft page as fast as possible, download the SP packs and just pray I don't get
wormed in the process. Is that your definition of
dandy?
And for real, there's little feedback to be made at this point. All the design decisions have been made so I would waste my breath quite frankly.
And for what I've seen so far from windows 8 and 10, there's very little of them that I am in major need of. XP to 7 is a sufficient technological and design jump (curiously, the biggest thing I love about 7 is how they copied mac os X's icons at the bottom bar, but in a way that makes a lot more sense than in the mac os, IMO) so that I cringe whenever I come back to XP, but I don't have that feel anymore regarding 10. Perhaps Cortana will smooth me with her chatbotlike manners but I somehow doubt it.
e: ALSO, someone could enlighten me if the "FIRST YEAR" clause to upgrades from 7 means we have access to Windows 10 for a year THEN we have to BUY IT at the end of it, or does it mean that we only have access to Windows updates for the first year? Or that we only have access to 10 IF we upgrade WITHIN the year?
Ah Microsoft, you're so good at marketing you don't even know how to communicate properly, wtf.
