Nathan,

> What are the physical dimensions and weight of the CharmIT Pro?

Sorry for the delay on this. A bit of background first. We have
an aluminum case design that was built for the original CharmIT.
This is a PC/104 based system. The case was originally set up
for two boards: a CPU board and dual PCMCIA PC/104 module. The
case looks like this:

The actual CAD drawings for the case are here
http://www.charmed.com/img/products/case.drawings.2000.12.20/

And this is the CAD viewer (warning: it's a 25MB download)
http://usa.autodesk.com/adsk/index/0,,837403-123112,00.html

As you can see, the case is an irregular shape, so it is hard
to describe dimensions. I just loaded up the AutoDesk CAD
viewer and looked at the drawings to find the dimensions.
I marked the dimensions on this photo:

So the case is really two sections, the part that has room
for 2 PC/104 boards is approx 4x5x2 inches. The other part
contains the power board, it is approx 2x5x2 inches. So
overall the case is approx 6x5x2 inches.

I don't have a scale so I'm not certain of the weight at
the moment, but it also depends on what you put inside
the case. The case itself is very light. The PC/104 based
CharmIT is two boards (CPU + PCMCIA) plus small power
board and hard drive. The CharmIT Pro is one SBC with
optional MiniPCI cards (very light). I will try to get
some actual weights and get back to you on that. It is
a lot lighter than lugging around a laptop for sure.

Regarding the CharmIT Pro ...

The CharmIT Pro is not based on PC/104 board architecture,
it is an SBC with MiniPCI expansion. We are using the same
case as the old CharmIT right now. Since there is only one
board (HS-1600), there ends up being quite a bit of room
inside the enclosure for add-ons. For example, we fit a
small USB hub inside, and there is plenty of room for more
equipment inside the case. We are now experimenting with
some new case designs that will be more streamlined for
the Pro hardware, but it will be a while till those new
cases are available. Eventually the Pro version will be
slimmer and smaller. For now we are using the case that
is in the CAD drawings and photos above.

One nice thing that we recently discovered is that there is
a new MiniPCI expansion card that allows for two add on
MiniPCI cards. This is nice because you can have for example
either a BT878 video card or firewire in one of the slots
(right on the PCI bus) and 802.11 or some other card in the
other MiniPCI slot. And you still have 4 USB ports and 4
RS232 ports, and 1 parallel port for the addition of other
peripherals. Eventually the new case design will fit all of
this into a smaller case, since it's not the PC/104 based
architecture: the SBC plus tiny MiniPCI are lot slimmer
than two stacked PC/104 cards.

Sorry, I was tired when I wrote that, the CharmIT Pro
(800Mhz Crusoe) is $2495 and the CharmIT (266Mhz Pentium)
is $1995. With a VGA display now down to $995, this is
within the price range of laptops.

As I mentioned, we are working on some new case designs so
the CharmIT Pro will eventually be slimmer and smaller. We
are also working on some interesting power ideas, but we
need to prototype before we can talk about what they will
look like, more info on that later.
