must check it out where would i go to look for one in Beijing and how much would i expect to pay, but i wonder how good the software is.
Can't help you much in Beijing, my area of function is mostly in Dongguan and Shenzhen. However I believe all the chinese cities are almost the same, so you could just ask around for this place called electronic city (电子城)and most probably you would find a great amount of look alikes in there.
Actually the software of the apple lookalike is so-so... don't expect it to wow you too much... it is an imitation of the real apple os, but of course as most imitation are... they are not the original and there are bound to be some bugs.
(Btw if you happen to come to Singapore again, perhaps you could visit a place called Sim Lim Square, which is near this Bugis MRT. Ask your relative, she should be quite familiar with that place. The Sim Lim Square is like a Singapore version of the Chinese electronic city where you might be able to get many lookalike and at quite a reasonable price too.)
