Is it worth switching to a Mac?
boundlessdreamz: For tortoisesvn there is scplugin. Last time I tried it was not as good as tortoisesvn. I just learned the command line commands and now I don't miss tortoisesvn.
http://scplugin.tigris.org/For SQLog you can run it on OS X using Wine. I have a written a guide on how to do that
