For example, the UMi X1, what has a bigger resolution screen, actual 1GB RAM (the I5 only comes with a combined 512+256, faked into 1GB by the system, if Andi took a look at the Antutu specs tab, he would have seen that the phone provides 1024MB usable RAM, what is impossible, given the kernel, etc, needs their own space, 920-950MB would be more believable).
Not to mention that GooPhone paranoidly controls every aspects of the firmware, you simply cannot get a hold of a stock firmware, so no modding possibilities for a long time. I tried to get into their forums, but without luck, you need to have a purchase code from GooPhone itself to be able to access the firmwares. It might change in the future, but for now, there are cheaper phones, with better specs, and with better aftermarket support.
