Laptops that will take 32GB of RAM

I have been thinking lately that it might be nice to have a laptop with 32GB of RAM, as most of the VMWare stuff that I'm touching these days needs the host to have more than 16GB (VC Ops and vcloud director for example). I have a home lab but I it would cost MORE to buy 4x8GB sticks for that than it would to buy 4x8GB sticks for a laptop (I am conveniently ignoring the purchase price of the laptop of course!).

The below is a list of laptops that have 4 memory slots, and in most cases, Quad Core CPUs (some are Core 2, most are i7 - I believe only the i7s support 8GB per channel. I've left the Core 2s in as they are a lot older therefore cheaper and 16GB could suit some people).

I'll try to keep it up to date, at least until I finally purchase one - I haven't found a list as comprehensive as this one.

**Good tip for finding number of slots**
Google one of the below;
i7 "4 sockets" site:memorystock.com
i7 "slots: 4" site:crucial.com

**NOTE BEST**

1. Some of these laptops are available with different CPU types - to take 32GB of RAM it HAS to be a QUAD CORE i7 (ONLY the i7 was\IS available as a quad core, BUT SOME i7 chips are DUAL core - even if a dual core laptop has 4 slots, only two will work and i7s can only take 8GB per channel. Quad core i7s usually have QM in the name).
