I have not seen a Sony Walkman since 2002. I have also never seen a Creative Labs player, even into today.
What I saw was in the UK, before I moved to China. In the early days of the Walkman PMPs, they were awful. Very proprietary. Once they dumped ATRAC and their dreadful Sonic Stage software, they were actually good IMO. Creative Labs were quite common as well here. iPod was also very popular as well of course. I still got an 80GB HDD iPod that I use sometimes, although it's not using the Apple software, I got Rockbox on it.
These days though comparatively few people use PMPs, we're all using our smartphones now.

How long was the Zune out for? - two years was it? But as I said, I never actually saw one, just read about it. Windows Phone in the PRC is quite a rare item so far, or so it seems, and not being marketed very well. The local Unicom dealer has a few non-functioning dummies on display, This is in amonst many functioning demonstration Androids that customers can play with and try out. There's real iPhones as well. Chinese manufacturers(except for Huawei) don't seem to do any Windows Phone handsets so far, they're almost 100% Android now.
