Some people don't see the glass half full... some people don't see the glass as half empty....
Some people see the glass as completely empty! (perhaps a reflection of their lives?).
The only angst I see towards Yamaha is that they refuse to make a 76. Ian proclaims that will not change, so there doesn't seem to be much to obsess over. To be honest, the Yammie owners seem to be a fairly quiet, probably very satisfied bunch. With this much contentedness floating around, and the T2's pretty contemporary OS (there's very little that is missing from it's OS compared to newer arrangers), the clamor for a new Tyros seems pretty muted.
Plus, of course, with Yamaha you can clamor all you like (76-ers unite!) and they will take absolutely no notice of you...
Me, I just think the glass is twice as big as it needs to be!
