I did not like the first release of Windows 8, I changed my mind with 8.1 update, and I’m happy with Windows 10 Technical Preview build 9841, because now it is all about desktop (when we talk about PC) and things look good. I understand it could be buggy, but I’m not afraid to be a bit vulnerable. Besides, it runs smoothly and I can do whatever I used to do before without a glitch. Of course, it is a prerelease software, and as Miscrosoft warns “trying out an early build like this can be risky. […] don’t install the preview on your primary home or business PC. Unexpected PC crashes could damage or even delete your files, so you should back up everything.”
So, please make an extra backup if you choose to install it.
