I upgraded to windows 8 when it was only $39. So far the App Store isn't impressive yet. Not too many developers have made apps for windows 8. I wish it would catch on enough that more app would be made.
I've had a lot of problems on this site if I'm not logged in so it's the only reason I have board express installed, in the off chance my session has expired. Most sites on my W8 tablet I just go to in IE.
IE10 has issues with sites too though.
Even in Tapatalk, some things are wonky. Participated threads isn't in the last updated order like on other sites.
