I absolutely love my old T400 notebook, this is why I stick with Lenovo. Unfortunately this new model is big disappointment, and a very expensive one!
I paid around 1k euros for mine with GTX730M and core i5.
My goal was to find a compromise between work and gaming system, this laptop is a mixture of both but far from both ends.
As for a work laptop, do NOT buy this laptop if you work in linux and you regularly need the F1-F12 function keys since these are only available with holding down the Fn button. I don't get it why did Lenovo remove these very useful keys.
Second is the LED status indicators, working in the IT you just want to know what is your laptop doing (regardless what's on the screen). Is the hdd loading something, are you getting packets on wifi, is the capslock turned on. On this laptop there is no indicator at all!
The touchpad is completely unusable, I'm not a pointer user like many other ThinkFans. The touchpad is so sensitive that if a second finger or palm gets near it it notices it and since it isn't a multitouch programs will act stranegly like you will be thrown on your workspace 3 in kde.
You need to get use to keeping your second hand way over it. The rightclick leftclick on the touch area doesn't work as intended as well so if you planning on getting this laptop you might need a normal mouse.
How does it perform on the other end as a gaming computer? Well the 730M takes Skyrim well with Ultrahigh graphics although the fans are really noisy. Also if you use your laptop for gaming then you definitely looking for SSD or SSD+HDD hybrid solution since Windows7 bothering the disk all the time, even with disabling a lot of unnecessary services. The resolution of this isn't the best for videogames either.
The audio jack -as many people complained for it- driving me crazy. You basically have to decide if you want to play a game with headphone all the way or not. If you pull out your headphone there will be no sound anymore. You have to actually quit back to windows and restart the game again. For many games in fullscreen mode like Skyrim the ALT+TAB doesn't work well which means you always have to close them if you want to do something in windows. I'm not sure that it's related to the optimus driver or win7 or the game but I never had these type of problems on my desktop machine.
One of the part where the thinkpads having the greatest disadvantage is when you switching between OS-es. This laptop for example puts the usb port in a state where your usb mouse works from linux but if you just reboot the laptop into windows the mouses lights doesnt show up and it's not responding (no matter which port do you plug it into). In order to get your mouse back you have to poweroff the laptop and boot into windows.
This laptop isn't really a compromise between gaming and work system (you can find much better type for both). Also with brand new battery, with regular usage (youtube, music, videos, some gaming, internet) the battery last about 2 hours. If I would have to put this on a scale from 0 to 10 where 10 are the gaming systems and 0 are the work systems it would be somewhere on 7.
If you are big lenovo fan and love the thinkpad logo with the blinking led and the chrome cover and you are looking for an entry level gaming laptop that's the only case you should buy this one.
For work there are hundred times better ultrabooks and for gaming there are hundred times better desktop replacement laptops.
