The U2's (http://www.hardkernel.com/renewal_2011/products/prdt_info.php?g_code=G135341370451 http://www.hardkernel.com/renewal_2011/products/prdt_info.ph...) are great, and the performance is a substantial multiple of the RPIs. One of the issues with arm is that its a whole separate world of compatibility and performance from x86— it's easy to get a order of magnitude less performance accidentally if you're not careful with what you're buying. I'm sure the same is true for x86 too, but people coming from that background have the experience to avoid it. I'm really looking forward to getting a Cortex-A57 based U2 like device, aarch64 sounds fun.
