heh, oh no I would'nt go that far, just simply removing the LCD portion of 
the system, although, LCD screens, and the half of the shell that would be 
removed do not represent alot of weight, so its probably not going to be such 
a large problem

in regards to the proven concept of portable + HMD + Twiddler(or Twiddler 2)
like so many members of the list have tried, I was wondering, are there any 
known PDAs with a CPU clock at or higher than 100mhz that allow installing a 
secondary OS on the flash rom that holds the OS, unless you use a Zaurus 
which already has a fairly suitable linux distrobution
I have a Casio E100 and like the E110 and E115, it does not allow reflashing 
a new OS to ROM, but that's ok I guess because all the BSD and linux kernels 
Ive seen that are for the E1** load from CF card, which is bad because then, 
what bus does the HMD use? after that you have a infrared port and a serial 
port (which needs an adapter) so if you need networking you have to figure 
out how to share the Compact Flash bus with two devices, once thats 
acomplished all is well 

really, all I would have to fulfill is storage, HMD, input device, and 
networking
the serial would probably go to the input device, but theres hardly any room 
for the others
this why I almost always favor an embedded board over a PDA
untill PDAs start coming with PS2 connections a board like a laptop or 3.5" 
embedded PC is probably easier to use

<BR>Putting the MB/parts into a different enclosure takes time which
