The ARM hardware gets better and better, but stuff like storage continues to be (comparatively) grim. If you think that compiling from an SD card is fun, I dunno...
We have no ATA or SATA buses on this beast - if you want serious storage, it's USB, or slum it with NAND or SD.

So stop using big HDMI displays, when you could just X in and open a window on your desktop machine.
While I do care about power, if the product becomes unsaleable because of a power compromise too far, we've lost, not won.

Or plug an HDMI chip onto the DSS bus connector. I'm not trying to rule it out completely, I just don't want HDMI fitted as the default. Heck, Beagle has _no_ way to deliver HDMI, it simply used an HDMI-shaped socket. We're offering more, not less.
We'll have SDTV inherently (costs me a couple of resistors and a connector).

Ethernet is provided, Beagle-XM-like, on a USB hub chip. This seems to work fine (although I don't know if the Ethernet comes alive during, or after, boot).
You'll get 2 direct Ether ports to the OMAP, and the third will go through the hub, producing Ether 10/100 and 4 more USB ports. If you want more than 6 USB ports, you'll need a (powered) hub.
The resources on Challenger will obviously be mission-appropriate. Start campaigning for what you want, I don't care much (yet).

Yes - an alternative is a USB-connected monitor. Which Nick has working. And it doesn't need 240MBytes/sec - it's a remote framebuffer, and only needs updates. Same as a remote X display, or a VNC framebuffer that doesn't get written out to an actual display. So many alternatives to dragging another monitor onto a crowded desk and finding cables & power for it.

Serial terminal for first boot, and after that there are many, many choices, of which HDMI is probably the most crappy.
