I had about decided Microsoft was going to DUMP Windows 10, and maybe they should.
I've been beta testing since Windows 95 -- except when they decided to demand we PAY THEM to beta test and I told 'em where to shove that -- and have never seen such a long time between releases. 2 weeks was the average time between beta releases on most versions of Windows.
What is the point of being an Insider to test W10 if there is nothing to test?
Going 2 months between releases made me pretty sure that they ran into some darn big problems ... and they were pretty obvious. Cortana DOES NOT work. Spartan was not ready ( don't know if it is now or not because we haven't been able to play with it, although I understand there is a way to get it but I haven't bothered because I have been disgusted with the lack of new builds ) and Continuum is just someone's wet dream and doesn't appear to be anywhere near release.
Other than those things, W10 is just W8.1 with altered user interface.
It may be a bit prettier when finally released --- who in the hell did the graphics for the Settings in W10 -- black and white line drawings. But nothing substantially different.
W10 still uses NFTS file system ... did NOT go 64 bit exclusively and until it does it is going to remain hampered in some respects. Although doing so will cause us all major headaches as we lose old 32 bit programs.
To add to the problems, I have two programs from Nuance --- Dragon Naturally Speaking and Paperport which I use all the time --- especially Paperport and they do not work with 9926. If they don't work with the final release version of W10 I will remain with W8.1 because I'm not going to spend almost $500 for new versions of those programs ... at least not until there is no other possible option. If the only option is to forgo W10 == well no bigee because I don't see anything that revolutionary in W10 anyway.
Really, I Mean it, I'm not kidding, don't laugh, I'm serious.
