I realise that this is going to boil down largely to personal preferences,
but I'd appreciate suggestions please.
In many years of PC usage I've never owned a laptop. But I'd now like to
treat myself to a reliable, high spec, i7 model. Apart from top end
performance, large RAM and HD, other factors that come immediately to mind
are an impressive screen and that it should be as easy to use as possible.
(For laptops, that last one is probably hard: the main reasons I've never
had one is that I'm useless without my mouse!)
I would have considered a 'netbook', as internet capability and
portability are also important requirements. But I understand that
category wouldn't cover my high performance spec (which I need in
particular for video and DVD authoring.)
If I'm OT for this group, my apologies. Perhaps someone could point me to
a group or forum where I'm likely to get objective advice please?
What I'm doubting, is you could ever have enough horsepower in
the laptop, to keep you satisfied.
If I check a "boutique" laptop like this Alienware, the fastest processor is a 55 watt one...
I think the XM means the multiplier is unlocked, for overclocking.
Not something you're likely to want to do, in a laptop, due
to cooling issues.

"Intel Core i7 2960XM 2.7GHz (3.7GHz with Turbo Boost, 8MB Cache)"
In a desktop, you could have this 2600K for a lot less money.
Intel Core i7-2600K Sandy Bridge 3.4GHz (3.8GHz Turbo Boost) LGA1155 95W Quad-Core

With all cores flat out, they run at the base rate. So the desktop
one would be 3.4/2.7 = 1.26x that laptop. (Turbo is for lighter loads.)
On the "regular" web sites, you could look in the business section,
for a "Mobile Workstation", to get the 2960XM as an option. When
I tried to configure one that way, the price was higher than the Alienware.
You can find other firms, that will customize a laptop in a more
imaginative way. For example, the Eurocom Racer model. That
got the price down to about 2/3 of an HP Mobile Workstation
(because it's not using OpenGL certified graphics for CAD work).
The graphics in the Racer are modular, and use an MXM module.
That's how they can plug in the graphics option, when building
the machine.

Companies like Eurocom, don't make the basic machine. An "ODM"
like Clevo makes the platform (in this case, in a modular
way), and then the OEM Eurocom, builds the final product
by installing what you order. It's like Clevo builds
the "barebones" machine, and Eurocom plug in CPU, RAM, graphics.
The Eurocom one, uses a 180W AC adapter, while the HP Mobile
Workstation I was looking at, had 200W and 230W adapters. Just
to give you some idea, how much hotter these are, than a 65W laptop.
When the graphics on those things, aren't cranking DirectX games
or doing OpenGL certified CAD engineering designs, they draw a lot
less power than their max power rating, so it's not like a 230W
laptop, draws 230W all the time. Probably closer to 50W at idle.
It draws the 230W when you're playing Crysis. Or a lesser number
when editing/rendering video. It really depends on whether any of your
software uses GPGPU computing (stream processors inside GPU), as to
whether a high end graphics solution would really make sense.

In the "it must be a joke" department, there was an April 2011 announcement
of a laptop with dual processors in it (two sockets). But the hardware
configuration is too outlandish to be real. I couldn't find this on
their web site. Price starts at $8000. I bet the keyboard is
too hot to touch.

There's enough cooling in this picture, to run that kind of
hardware. But only one hard drive is visible. This is a
Eurocom (Clevo) from 2009. This one weighs 12 pounds.
No mention of battery life. You're likely "tethered" all
the time. The exhaust goes out the back.

Maybe that's the trick. If they didn't have a battery,
there'd be more room for other hardware.
