There's nothing here yet
I have been using the technical preview as my secondary OS for a couple of days now, installed all drivers for Windows 8.1 and up until now everything works very good. It actually runs very similarly to Windows 8.1.
All software I use everyday works fine, no issues whatsoever, yet after a couple of hours (5+) of running, it becomes a little but sluggish, applications take longer to launch - sometimes they don't at all.
Reboot solves this problem.
There aren't any BSODs as of yet and no major problems.
I will continue using it more and more as a daily driver and report back
... what are your opinions guys?
Thanks for reading - Bart.
