Having used Mac, Ubuntu and 2 other flavours of Linux, I'll always come back to windows. Mac and Linux for me are alien OS's and require a steep learning curve involving a lot of time and patience. Windows, I can troubleshoot easily, if I can't, a google search usually does the trick.
Count me out as my laptop does the job well, I see no useful purpose for an I-pad. I refuse to pray (or pay) to the Church of Apple.
