zbrush + lenovo tablet pc

Hi guys, quick hardware question.
I was thinking of buying a tablet pc and have managed to whittle it down to the Lenovo thinkpad X series. But i’m stuck between the X200 and X201 tablet.
I’ve been asking around many forums and theres hardly any difference between the two apart from the x200 has an intel core 2 duo cpu and the x201 has an i5 cpu or i7 cpu depending on which model you choose.
Looking on ebay theres almost £400-500 difference between the two.
The x200 I’ve seen on ebay has the following cpu:

Core 2 Duo SL9400 1.86 GHz
4GB Ram

And I was wondering if anyone had any experience with this cpu and zbrush?
What poly range could you get to before zbrush became unstable?

Thanks for your help!

Does anyone have any experience using this cpu and memory on a desktop, not bothered whether its a tablet, laptop or desktop, just want to know if it can zbrush well with millions of poly’s… and if so what stage does it become unusuable?

Thx!
