I've decided to ditch my work pc for a Mac. But I have 2 questions: 1. Buy now or wait till the next MBA release? Is that April? 2. Should I get a pro or an air I use my work computer for excel, outlook, PowerPoint and the web but I multi-task a lot. I usually have multiple workbooks, powerpoints and web sites all up at the same time. Will also have to use Citrix or Parallels to access Siebel and sharepoint. I would ideally like an Air but don't know if it will run fast enough for what I do. Thanks!
