Hi, I am undecided as well between MacBook pro 13" and the Lenovo X200s. As someone has said in my case it's about battery and portability (pros in Lenovo) vs beuty and superior OS (pros MacBook pro).
Even always been a PC guy, though, I am much less scared of the adjustment to a new OS than the rumors about MacBook pro defects. Have you ever read the list of them at
http://appledefects.com/wiki/index.php?title=MacBook_Pro#Defects?
Even if I am curious to give Mac a try, the list is pretty scaring. And moreover, scanning the internet, I have found nothing comparable about Lenovo X200.
Do you guys have any opinion in such respect?
I was seriously considering getting the X200t in Sep last year when I needed to Upgrade but went with the MBP mainly for the horsepower as I needed the Power more for Video and Photo work the The Mobility and Tablet features afforded by the thinkpad. Also, I was able to get the MBP cheaper the the Thinkpad at that time in the UK due to the Student Discount (None available from Lenovo).
Having said that, If the Prices had been comparable, the decision may have been toward the thinkpad as I've been a PC guy for years, and Familiarity has its advantages as even after 4-5 months I often find myself Thinking how the $%^& do I do this on my Mac. While I do enjoy my Mac and Like some things on it, at times I really do get fed up as I need to run something I need under virtualization as it or s substitute is not available for OSX.
Heck I'm saving up My self to Either get the New X201 Tablet when it comes out later this year, or to get the X200t with multitouch if I can score one at a good price to use as my mobile work machine as the office and Most of the Apps we use are PC only so I can dedicate a machine to that and use the Mac as my Media creation machine.
So in your Case i'll suggest Considering a few things befoe making you decision.
* Mobility - How important is Mobility. If its a key need then the Thinkpad has an edge as its lighter can be used in Tablet mode even in very cramped spaces. While the MBP is portable, its still a heavy machine, and does require some space to open.
* Battery life - The Thinkpad is going to give you more battery life plus the ability to get an extra battery to swap out if you need even more run time. My MBP on average gives between 2.5-3.5 hours depending on what I'm doing which is usable but does require me to carry my Power brick with me.
* Performance - You are definitely going to get much better performance from the Mac. If you are planning to do a lot of Media work, Rendering, etc then the Performance is going to be important. If you are mainly doing Word Processing, etc and occasionally Photo or video editing then The Thinkpad should more then meet your needs.
* OS - If you are familiar and comfortable with either OS its going to affect you choice. No matter how frustrating I find Windows at times, Its still the OS I'm most comfortable in and find easies to use. I was willing to try OSX as I wanted to learn, as Tech is my Hobby. If you arewilling to switch to anew OS and learn its quirks then do consider a Macbook and OSX. Do keep in mind that its as complex as Windows in in its own way and requires learning how it works.
* Keyboard - I personally feel that the Keyboard on the Think pad is much superior. While I can and do use my MBP keyboard pretty well, every time I end up using a thinkpad for even just a little while I'm surprised at how good they keyboard is to use.
EDIT:
I forgot to add earlier, For a good comparison of using a X200 Tablet and a Macbook as well as how they stackup against each other in the real world Check out what James Kindrick of
JKOnTheRun has to say as he's regularly using both in his workflow.
Just search for X200 and Macbook at the Same time to get some of his thoughts.
