Was just looking around technet / msdn, and noticed a customer preview is now available, for the new wave 15 server products, give it a download and see how you get on.
Url to downloads
Office Web Apps 2013
And you can also install it with SQL 2012, if your feeling really brave.
See here for links to the trial version, and here for the instructions
Early bird discount now expired so ful price $1895, here’s hoping my employer allows me to attend this year. Looks like it will be a great event and a chance to see SharePoint 2013 (Wave 15) in action for the first time.
Have you ever come across an issue where a folder becomes inaccessible via webdav on SharePoint 2010 server if the file name has a ascii character 63 in it?
If so please comment, and let me know how you fixed it.
