Questions re. R61 15.4" ws (8918-CTO) - 4-in-1 reader,

[basketb]

I am currently looking into getting an R61 w/ 15.4" wsxga+, nVIDIA GPU (8918-CTO). But before pulling the plug I have a few questions:

1. Does it come with a 4-in-1 reader? The Lenovo customization website does not offer an option for this, nor does it mention one on the order summary page (whereas for a T61p it does). But I have seen references to it on 8918-xxx models.

2. Can I replace the screen with an 15.4 WUXGA screen? If so, would this also be possible if I ordered it with a 15.4 wxga screen.

3. Does anyone have experience with the UltraBay Blu-Ray burner as blu-ray player? (e.g., connecting an R61 through an advanced mini dock to an HDTV using a DVI->HDMI adapter)

4. Is there any reason to get a T61/T61p w/ 15.4" wsxga+ screen over a similarly equipped R61, if size, weight, and battery life do not matter?

Thanks.
