X200T slower than earlier Thinkpads rendering video?

Question:

Can the X200 Tablet be slower than many earlier Thinkpads when rendering video?

1 We ordered a X200 Tablet 7449-C4G (Win 7 Pro x32) with a view to using it as a high quality presentation platform for training and marketing.
This would replace an X60 Tablet with the benefit of a faster processor, built-in 3G and a built-in Web Cam
2 Upon completing the setup and installation of Anti Virus, Office 2007 and Microsoft updates we observed:
a. The screen is not white, but between off-white and grey.
b. There is patchiness on the screen.
c. The performance generally is not as fast as on X60.
d. Default screen background (Windows Classic) the X200 is lighter cf deeper.
e. Films & Videos I ARMREVOLUTION loads 2-3 seconds slower on X200.
f. The video takes 30 seconds more to load
g. The picture quality is grainy.
h. There are flickers and breaks between frame transitions, i.e.
the presentation does not flow smoothly.
i. Downloading a program took 6min 30sec more than X60 which did it in 49 sec.
3 We concluded that there was a serious deficiency in the overall quality of the X200’s performance and there repeated the above test with and X41 Tablet T61 and a T42.
4 All the tests were performed with the system set to maximum performance, AC power and wired ethernet to the router.

Can any expert around shed some light?
