Having spent most of a day now in the World of Windows, I once again realize why I personally do not want to use a Windows machine again, ever. Windows is an unmitigated pain in the ass, sometimes I think intentionally so by MS's past plans and business decisions.
This is the second time I have said "you jest keep it" to MS's attempts at getting me to upgrade to Win 10.
I know I am not a typical "computer user" anymore but if they really want to suck everybody into Win 10
they need to make it a lot easier to do.
=========================================
I am also stubborn and persistent ...... I finally got the Vista machine to create two bootable DVDs of Win 10 Preview (one 32 bit and one 64 bit) that the Vista machine can read.
(Note: this does not mean the older XP machines can read them -- but the Vista machine that wrote them can)
Wife and I are discussing it -- she doesn't want any interruptions to her life and
"I don't want to learn anything new -- I am 3 years away from retiring, so screw it."
She lives off her phone and iPad now while laying on the couch watching Downton Abby and only goes upstairs to use her PC every other day or so for something the iPad simply won't do.
Like most of us, we don't want to learn anything new or more complicated.
=========================================
Ironically, the 64 bit ISO image Win 10 can be read by both my old 15" laptops (one Vista, one XP) with the XP machine
grinding very slowly while loading the Win 10 preview.
The irony is that both machines run Linux Mint quick like a scalded dog --- but the new "improved" Win 10 runs like thick cold molasses on the same machines.
Win 10 for PC is NOT lighter or faster, indeed, quite the contrary -- it is BULKIER and slower even.
=========================================
If you have a late Vista machine or a Win 7 machine, you can go to Win 10 with only a somewhat irritating noticeable performance penalty using your cruffed up old Vista and Win7 machine as a comparison point. Linux on the other hand smokes both the old and the new windows, running well on the Win7 and Vista grade of machinery.
XP machines need not apply to convert to Win 10, you will fight like hell to get it loaded and then be disappointed in the way it runs --
go to Linux on the old XP machines instead and be pleased with the upgrade in speed and performance that you will see compared to your old fragmented, cluttered & choked down XP installation that you upgraded.
Is Win 10 a reason point to get a new machine? Not if your old stuff meets your needs and you are happy with it.
Upgrading to Win 10 may cause you to get dissatisfied with your old stuff as it is slower and "somewhat lacking" when trying to run Win 10.
Remember, once all of Win 10 gets out there completely it will require a microphone on every PC so you can talk to Cortana, and a camera so you can video Skype etc. etc. etc. Upgraded older machines will lack mics and cameras and all these other "get to use all the full features" support hardware items ....
Should you even be considering buying a new PC period, considering what is coming up in the next year or so? No, you would be buying a new copy of an obsoleted technology. If you are "buying the future" simply chose your next cell phone very carefully and roll with that pathway going forward.
