I know this is an old post, however I had to respond. I am a long time user of Thinkpads. I started with my first over 15 years ago. They were always at a premium price compared to other Windows PC's of the time, therefore I took very good care of them. They are built like tanks. I still have everyone one of them, and each and every one served me well.
That being said I recently purchased my first Mac. It is an older MacBook Pro Core Duo and love it. It is built every bit as well as the Thinkpad. My wife has a new T510. Either is a fantastic piece of hardware. I really love this MacBook Pro. The screen is fantastic. It is small, light, fast, looks great and I really like Mac OS X much better than I expected. The only thing I miss is the pointing stick as a mouse. I really liked being able to go to the menus on the Thinkpad without taking my hands off the keyboard. I am learning the keyboard shortcuts for the programs I use on the Mac, and I am actually faster because it takes me directly to the command I would have had to use the mouse to find. There was a learning time frame, of course.
For my day to day....Word, Excel, Web, email, programming, iTunes and photos..my Macbook Pro is the perfect tool. I don't miss the Thinkpad.
Have a great day.... 😉
