Tea... I agree that all these machines are capable, and that we would adapt to any of them and be pleased with the high-quality digital results. It's a wonderful time now for us musicians, isn't it?
But with all due respect, I don't agree that they're all as close to equal as you surmise. During the past year, I researched all units in this price range, reading every mag review I could find on both sides of the Atlantic and visiting quite a few music stores in the southern Cal areas. I'm a writer by nature, so research comes naturally and I enjoy the process.
In short, I bought the 16G after finding nearly perfect agreement among reviewers and store employees: the 16G leads the $1K pack at this time. Add to this a fantastic support group/site, and
I think the decision is a rather easy one for most to make--hence, the current backordered status of Yammies. I share these thoughts here not to feel smug or argumentative, but only to help those who find themselves on the fence needing to fall one way or another. Of course, it's just my opinion and all are free to ignore it.
Peace,
