Lenovo or Mac?

Time to pick a new laptop at work. This time, even engineers can pick a MacBook Pro instead of just a list of Lenovo ThinkPads. To many people the choice is pretty much a no-brainer but to me, it's a tough one. I have not used a Mac for 13 years!!! I worried about the number of applications supported and having to form new computing habbits. I don't need to be "cool" but just want to get the work done quickly and effectively. I have only till end of today to decide or it will be defaulted to the cheapest Lenovo model on the list ... :-(

**Ok, ordered the Mac...
