Well, I'm waiting Mer too but I have become little bit sceptic about it lately. Maybe it's the lack or Mer related news here in TMO, I don't know. Seems that the focus has shifted to N900 also in Mer development (OpenGL 2.0 ES required currently for example). Actually, I'm just damn impatient and making up excuses. Hopefully Mer will be usable also in N8x0 soon.
