"Too much in one fell swoop. Learning curve vertical."2.5 starson by Diluvium
Pros: Accepting that 100 % would be Utopia, most major programs passed upgrading from 7 to 8 well and worked without a flaw.
Cons: Upgrading from 7 took much longer than advertised and ended up having to be undone. I had Cons. Prev. installed on its own, on a different disk, but somehow the upgrade from 7 to 8 RTM got intertwined. Windows 8 RTM became unbootable. 16 hours lost.
Summary: Needing some diversion, I wanted tom play a bit of Solitaire. So, I click on the 'Games' tiles. No Solitaire there, but something to do with online gaming. A search for Solitaire yielded no result.
I was pleased to see that the desktop had survived the upgrade relatively well, but the carefully tweaked fonts and colours of the various components of a window had got lost.
There appeared to be no obvious way to change system fonts, or, at least to change them to a serif version, my time was insufficient to really search deeply.
Some of the new programs seem to suffer from PUD (Programmer/User Syndrome). But that I mean that an excellent programmer does not quite understand what the user wants and the user is not able to write what he want in a way that a programmer can understand. One end up with a program that looks nice, but is actually useless. This phenomenon is not new of course, but has persisted since the 1960s, when mainframe programming came on stream.
The concentration on touch screens has not been thought through that well either. I have a four-monitor setup, giving me effectively a 7680 x 1080 screen. Even they were touch screens, they would have to be at such a physical distance to be comfortable to the eyes that my arms would be too short to reach them.
Although Microsoft might like us to think otherwise, just this point proves that the business user, who is its biggest source of income, comes as a kind of afterthought. Just try picture someone, who is putting long and complicated Office documents together. May of those people don't like to take their hands off the keyboard. They will only use the mouse if need be. If the whole caboodle goes touch screen, it will become necessary to rise from the seat and half lean over in order to operate the touch screen. There probably won't be a stylus either, so anyway who has slightly fattish fingers may have to make several attempts to find the precise spot within a word where the cursor should go.
Their is fair chance that W8 will go the way of XP, which, Microsoft must think, has significantly outstayed its welcome. Except for youngsters, who think a desktop is just a big mobile phone that is somewhat awkward to carry around, I would recommend to anyone who is still on XP or Vista, to upgrade to 7 and not to 8.
Back to the Cons. The actual upgrading took just over two hours, not 20 - 40 minutes. Windows 7 and Windows 8 Cons. Preview each had their own entry on the Windows boot loader. My actual experience has shown that it is ABSOLUTELY INDISPENSABLE to make a full backup of system volumes and to create a recovery disk. Luckily, I had done so and restori8ng Windows 7 merely took time but no pain.
However, getting rid of the Windows 8 Consumer Preview caused GRUB in the MBR to be overwritten by the Windows boot loader, which required yet more time and some trickery to get GRUB put back there, so that it was possible to boot to my Linux installations again. The entire process from starting backing Windows 7 to getting back to the starting point took exactly 24 hours, of which a mere five hours were spent sleeping.
So, anyone who has slightly more than a single installation, with nothing else on his system, to upgrade, should take all possible precautions.
