New laptop decision help

[Caboose]

I'm looking into a new laptop that i will purchase towards the end of July, 

My main choices are

1)Dell Xt3- HORRIBLE battery life, would have to spend nearly $100 for a spare battery slice,No Webcam, good looking aluminum build,Tablet funcionality.

2)Thinkpad T420-Amazing Battery life, reinforced plastic, So many ports, The amazing keyboard. 

3)Hp elitebook 2760p-The only one I have seen in person,Decent Battery life,Slim Battery Available, Tablet Functionality,Legacy Ports.

4)Thinkpad x201t-First Gen i5, amazing keyboard, Great battery, Tablet Functionality.

 

Im having a hard time deciding, my needs are great keyboard lots of typing, schoolwork, etc.

-Massive Hdd 750gb minimum

-Low end gamer Gmod, Hl2, Hl1, Counter strike.

-may dual boot android

 

I will take suggestions but be in mind my budget is $500 including Docking station, spare battery etc.

 

If your wondering i'm in the United States, Thanks for the advice!
