I have ordered one of these:
US $100.70 including shipping. But, be warned, I have been waiting 10 days since ordering, it still hasn't shipped. Dealextreme, I have learned, has a reputation for extreme slowness. So, this is probably not something to get while waiting for your RP!
Some guys have been able install Ubuntu on the Mele A1000:
It has Cortex A8 ARMv7 CPU, Mali 400 GPU.
I think that dealextreme don't keep much stock, so they have to get the item in from the manufacturer, which takes awhile. I have contacted them, suggesting that this is one item that they should have some stock of.
...and that's 100 USD with free shipping worldwide. I've just bought one as well, actually after dropping on your blog.
For the record, mine finally shipped on the 22nd March (I ordered it on the 7th). I chose the free post option, which is with China Post, which I now regret, as I have now learned they are also extremely slow. Dealextreme can send by EMS, but costs a bit more. Anyway, it is on the way.
Regarding the post about the SATA hard drive case, yes that is just a case, you will have to put in your own 2.5 inch drive -- that is one of the features that attracted me to this unit -- the Allwinner A10 CPU chip has a SATA interface.
Regarding hacking it, there is a group of about 14 guys who have just purchased these and they are going to be doing a *lot* of hacking. There are about another half dozen guys that I know of who have ordered it.
So, I expect that even if Ubuntu is not working quite right on it yet, it should be soon (well, I certainly hope so!)
Someone sent me a link to another vendor:
...these people claim to have them in stock and will ship within 48 hours.
