I'm a long time PC user and just ordered a 13" MBA 128/8GB. Very excited to see how it performs day to day. I'm gonna give the OSX environment a try and see how it feels. Although it hasn't arrived yet, I'm wondering what would be good APPS to download from the iTunes store. Both free and paid apps. One thing I will need is MS Office for MAC. I have a lot of these type of files. What are some handy or recommended APPS to download in general for a new or experienced user. Thanks!
