Comparing services of MS and Sony
The services comparing here is to Taiwan only because I get these information from Taiwan game discussion forums. Wii is not into this discussion because it is not released yet in Taiwan.
Due to the cause of overheating problems that some PS3 consoles having right now. Many players consult to the customer service department to request for exchanging new console. However the department replied to these players that they can only fix for them, and the exchange is not available. So then player reported to media, then post on news.
Some players who are more on MS side, saying that Sony never think about players in Taiwan because the market is so small, so not worth for them to pay attention to us; unlike MS, you are able to exchange as many consoles as you want as long as it realy has problem (the highest heard was 7 consoles). And one of them listed one action that MS did when xbox360 first out, having the problem of overheating...Acutally its not overheating, it is BURNING, x360's cable wires totaly on fire, so MS had to recall all the cables and give out to players for free.
xbox360 cable on fire (mandarine news)
Well, I mean, the cable is on fire man... its their responsiblilty to recall all the cables in same shippment. And in fact, this shouldn't even be happening, for this person giving MS credit on this, its ridiculous to me.
Anyhow, I think people should consider that PS3 is new released console, it contains new invented technology chips and blu-ray which is hard to produce. Additionaly, the first shippment almost all sold out on launch days and they don't have extra consoles to exchange with you even they wanted to! So the voice of complains soon reduced after the 2nd shippment arrive.
Second problem to these players are that Sony never like to have have games in mandarin edition. Unlike most games made by MS, they always consider about markets on mandarin speaker group. Well, for this part, I'd agree with MS people, cuz even if I can read english good, it is a 2nd language to me, so if I can read faster and understand better with mandarin games, why not?
Overall, MS does has better services than Sony, I think Sony should realy make improvement on it. And they do have space for improvement yes.
