What Thinkpad and battery/ies do I need to have maximum autonomy ?

Hello,

Everything is pretty much in the title. I'd like to know with what Thinkpad (and with what battery) I can have the best autonomy. I'm not interested by the laptops with the awful Accutype "keyboards".

I'm happy with the autonomy I can have with some of may machines. The X61s has great potential, the X200 too. The T400s is not bad either (I've two batteries in it). The X200s seems very nice but its very difficult to find one here in France (with 1400x900 panel), I wondered if I could have better with X201s orX220 ? Are there other machines I forget ?

Thank you !

X220 with 9-cell battery is good.
Thinkpad 25 with the 6-cell + internal 3-cell is even better.

Thank you dt_st.

I've bought one two days ago and I will receive it probably on tuesday or wednesday. And as a good news doesn't come alone, my friend told me he had brought me another X220 for my birthday !
I hope the batteries are still in good shape. We'll see that.
