Help: MB Core 2 vs MBP Core Duo

Alright guys, for the same price I can get:

1) Macbook Pro, 1.83GHz Core Duo, 2MB shared L2 Cache
15.4-inch TFT display with 1440x900 resolution
512MB 667MHz DDR2 SDRAM
ATI Mobility Radeon X1600 with 128MB GDDR3 memory

2) Macbook, 2.0Ghz Core 2 Duo, 4MB L2 cache
13.3-inch (viewable) glossy widescreen 1280 x 800 pixels
1GB Ram
Shared Graphics

Basically:
1) Primary use is work: excel, word, powerpoint, calc/pages
2) It will also be my home entertainment centre, hooked up to external speakers. All DVD watching and gaming etc. I live in a studio...
3) Want to be fairly mobile: to and from work on the train. Plane travel once a month.

I am leaning towards the pro, what do you think?

Reservations about it being 'refurbished':
A) Is the warranty/support any different? It says 1 year limited warranty...
B) Hardware, such as battery, HDD, superdrive should be as good as new right? And software should be current, not the older versions (e.g. Tiger 10.4.6 or sommat)

One other question, which applies to both: I'm buying it in Asia Pacific but move to Germany soon, will my support be valid there too?

Cheers!

If you plan on gaming the MBP for sure, its gpu will spin circles around the one in the MB. For everything else the MB should be faster.
