letcool support is thin on the ground, the manufacturer has released a couple of updates but still hasn't fixed some really obvious stuff like shoulder button support in the gba emulator. the reason nobody is developing anything for it is that it's too hard to do so. there is not really any documentation about the processor or anything else that is needed to base a community of developers on. unless there is some massive breakthrough then i would expect the machine to fade into obscurity within the next 6 months or so.
i would rather pin my hopes on the gemei a330 personally. it has already gathered quite some interest and it's not even released until friday (supposedly). booboo is willing to work on the a330 too, which is the selling point above all other selling points.
