Software sells hardware. It all depends on the software.
I love the theory behind the console and I wish them tremendous success, but unless there are some compelling titles that I can't buy on Steam or somewhere else, I don't see myself dropping $100 on yet another gaming device.
Then again, I have a PS3, a Wii (which also plays Gamecube games), a PS2, a Dreamcast, a PS1, a DS Lite, a Gameboy Advance SP, and a PC. My backlog spans that many systems plus there's a strong possibility I'll be buying an Android smartphone soon (even sooner than planned if AT&T refuses to return the 1500 rollover minutes that inexplicably disappeared from our account).
And most, if not all, of the features advertised would already be covered by the new-to-me PC I hope to (eventually) build. But I could definitely see how this could appeal to those without a HTPC or media center PC.
My own personal situation aside: I want this to succeed. I'm a big fan of open source and the following makes me want to give the project leaders a big manhug:
Hackers welcome.
Have at it: It's easy to root (and rooting won't void your warranty). Everything opens with standard screws. Hardware hackers can create their own peripherals, and connect via USB or Bluetooth.
EDIT: Read through more of the info on Kickstarter and I
really want this to succeed. Not sure if I'd drop $100 on another gaming/media device, though.
EDIT#2: Man, the more I read, the more I want one. I absolutely love the design philosophy behind this hardware. If I didn't have to be fiscally responsible, I'd probably buy one as soon as I get home where I could log in to Kickstarter and throw money at them.
EDIT#3: Hm, but what about piracy? Seems like with a USB port and the ability to root the device, piracy would be super-easy. Wouldn't that scare off some devs?
