SQL Server next version ‘Denali’ is coming up with very neat feature which can be used while presentations, group discussion or for people who prefers large fonts.
I have increased the font size to 400 percentage and for the same reason they are very large. You can adjust the font size which is convenient to you.
One more reason to go for next version of SQL Server.
