Regarding the RAM issue: Vista Home Premium is available in 64-bit flavor too right? Which version is shipped with Dell machines? Vista 64-bit will see a considerable performance boost with 4GB RAM in certain applications, right?
Another doubt: If the memory configuration is 1x2GB + 1x1GB, will it operate in dual channel mode? Or does dual channel require 2 identical memory modules?
About the Wireless card, how is the Wireless-N card better than the other cheaper card? Is the Wireless-N card worth the extra price?
Vista Home premium is shipped with 32bit version. EVEN IF YOU ORDER 4GB of ram. I dont know about ultimate. Also as techie said, there are no significant performance differences while using normal applications. Some games (UT for example) may show some improvements.
Intel uses something called Flex Memory Architecture to support Dual Channel on asymmetric memory modules. Although performance increment is less than what you would get in symmetric dual channel configuration (2*2GB for example) but is definitely more than single channel configuration. Read the following for more info:
Dual Channel RAM Guide - Notebook Forums and Laptop Discussion
About the Wireless-N, me and my boss bought almost the same config for DELL XPS M1530 except me buying a Wireless Draft-N 4695 and him buying a 3945abg. We dont feel any major performance difference in any case. Although in some cases (low signal strength areas...) I get an insignificantly little more throughput (which may or may not be attributed to 4695 adapter alone). Its just that his laptop cannot connect at 100Mbps to the new router in our canteen
For other standards (.11 a/b/g) there is no difference.

I have heard of some touchpad-related issues with Dell XPS laptops... And some heating related issues too. (From the reviews on the Dell site.) Minor issues or major problems?
Well there are minor manufacturing defects found in few pieces, but then haven't you seen a reebok show which got torn/worn out in six months? Plus, only the people who receive such defective pieces complain, the ones who are happy, only few of them say it out loud that its a good buy.
So you might receive a bump in palm rest, a Bad Screen (Its been the MAJOR issue with M1530 so far...), your palm rest might give you very feeble electric shocks (mine does.), heating problems, etc. etc. There is cure for everything and these reported problems should not deter anyone from buying M1530.
Also, I seriously believe that now when ram upgrade from 3GB to 4GB is just tad over Rs. 1.5K, you should buy 4GB ram (it would not be addressable but It would run in SYMMETRIC DUAL CHANNEL MODE...)
And also, I see good performance difference in my XPS (T9300, 2.5GHz, 6MB) and my colleague's inspiron (T8300, 2.4GHz, 3MB) but then that differs from person to person.
