Well I've been playing with mine for a few days, and it's very good indeed.
It's a pity it's shipped with a standard Raspian install on the MicroSD card as that means the little TFT screen isn't enabled by default and you have to download and compile a new kernel.
Initially I failed to cross compile it on my desktop, so did it natively on the Odroid-W... I left it over night!
I've now got the cross compile working on my PC, so it's only a few minutes if I have to do it again. :-D
Anyway, I'm very impressed with it. The battery life seems good, it lasted the half hour drive to work (the only real test it's had).
It really is such a pity if this little machine is going to be stopped by politics. I find the posts on the RaspberryPi forum incredibly short sighted... This is what open source and open design is all about!
The RPi uses Linux, which is open source, without it they'd have to write their own OS.
It really isn't going to steal RPi customers anyway... The basic $30 Odroid-W board only has one USB and no ethernet. So it's not going to compete as a cheap desktop machine.
By the time you've added on the RTC battery, the "UPS" battery and the TFT base board, you're looking at over $70. Who's going to pay that instead of a Pi? Only those that want a really compact unit. Who are now scuppered...
I've got half a dozen Pi's kicking about here, but now a potential solution to a specific project has been killed off, I think I might start looking at some of the other (more powerful) Odroid boards and migrating my code across away from the Pi platform.
So maybe the Odroid-W really has impacted potential RPi sales, at least to me.
