Well not until they get this external monitor mess cleaned up. If anything it is worse now.
For instance, if you drag IE between the SP and Desktop the scaling goes completely nuts and everything gets jammed off to one side. Def a BUG of epic proprotions. Also font smoothing in IE is HORRIBLE on my big monitor. I mean it is like there isn't even any font smoothing at all.
Ok, so far Windows 8.1 is a big improvement and is about as buggy as you would expect with a beta. Although faster, IE 11 is the most buggy part IMHO. Support for external monitors is really bad, worse than it was before.
So conclusion? 8.1 makes the SP a better tablet but not a better part of a desktop system (yet).
One thing I have noticed is that all apps seems to load quite a bit faster.
*Another thing: Metro Apps now will open on my external monitor if I have it set as my primary. Didn't do that before I don't think.
Ok this is kind of cool on dual monitors. Whichever monitor you click the Start Button on, that is the monitor the Metro Start Page opens. They really need to fix their font smoothing algorithm. It's terrible. Text in IE on my big monitor looks AWFUL.
I am getting error 0x8020002 1/3 of the download from the Store. I don't know why and didn't ask Microsoft, but I'm now downloading the ISO from my MSDN account to try it that way. Perhaps a better way as I can now boot Windows 8.1 from VHD and keep my Windows 8.
