I'll leave the eliteness of anything Dell to others.
But, what would be my dream system, assuming it to be reasonbly portable, integrated and self-contained. By that I mean its not to bulky or heavy to reasonably carry around (ie - not any bigger or heavier than a typical attache case). That may be too big for some, but let's face it, if this is your office, your world, its got to have some volume and heft. That's what my machine is to me.
So, yes, its got to have at least the capability of operating on batteries, though I'd see those as external attachables. A thin (1/4" to 3/8"), flat sheet approximately the footprint of the machine that would securely attach and perhaps allow multiple units would be perfect. If you are about home or the office (for me, that's one and the same), you have at most 1 unit. For traveling, perhaps you attach two or three, with maybe more in your other carryon. Kokam has a 250 Wh LiON battery that's 13 x 18 x 1/4". That compares favorably with something like the SAGER 12 cell battery with about 100 Wh. I'd prefer 12 volt input as well, just to make using cars and other sources simpler. Why have to carry an extra adaptor?
For a screen, I'd want as big and as high a resolution as possible. I'd say 22" wide screen with at least WUXGA. That would be driven by the best GPU I can stuff in the bugger. With the attache case size, I should be able to use a standard desktop mainboard and with that, something like an ATI 9800 Pro AIW or a Fire GL. 256 MB RAM, naturally. It would be nice to have built in connectors (both DVI and structural) for additional screens, one on each side. I think three ought to do it.
For a CPU, definitely an AMD FX, perhaps a dual core or even dual processors. As it will be a desktop mainboard, I should be able to fill it up with RAM, on the cheap as it will be regular DIMMS, not expensive SODIMMS.
Drives, well, at least two in a RAID 0. I don't really see the need for more than 60 Gigs, though I'd definitely upgrade to 80 or 100 when those become available. A good External Drive Enclosure can handle the big time storage as well as perhaps a nice little file server on the home office network so anytime I need some to access something arcane, I can do so via the internet and wireless.
Which brings up the wireless, 802.11 g for sure, preferably turbo'd. There'll be plenty of room for the antenna, prehaps even a fold up, telescoping one.
A suite of media drives, the typical record/playback and playback only pair, I don't see the need two record two discs as once. But, hey, if money is no object, why not?
I/O, 4 - USB2 (mostly for external keyboards and pointers), a pair of FireWires (for External Drives) and a pair of Express Card slots (for anything else), with maybe slots for CF and SD chips. SVid in and out with dedicated TV audio in and out. Plus a separate set of audio plugs specifically for multi-channel sound. A separate set of headset plugs (two, for those intimate moments).
Naturally, cooling is going to be an issue. So the screen lid backing would be a folded fin array with a small manifold fan to reinforce natural convection (the channels would run up and down with the screen lid open). Plus the case would be aluminum with a substantial set of fins running around the exterior. Both the lid fin array and the case would be connected to central heat sinks via multiple (perhaps a dozen) heat pipes. Perhaps with peltiers on the downside to accellerate heat flow. That will keep the heat of the peltiers out of the case. I'd like to see the interior of the case, where the guts are, sealed so nothing gets in there. No dust, no bugs, nothing. Easy enough to provide a small equalizing valve for altitude and pressure changes.
I haven't any use for the audio DJ setups. But I'd like a locking lid. Something secure. Oh yeah, a built-in 102 keyboard (removeable and wireless would be nice). Plus a large (2.5" x 4") touch pad (attached to the removeable wireless keyboard).
Well, that's my dream machine. Hope to have something at least somewhat similar next year. We'll see.
Oh yeah, I forgot about the three solid state drives, probably 1 or 2 gigs each, for OS, swap and major programs. That ought to take care of it.
