I agree about waiting... I bought my G5 when I read less and less complaints about it, that was 6months after the release, never had any trouble with it 😉
Its just like cars, they put them in production, but never buy the first series 😉 my brother used to design for Toyota, so he knows (and all car manufacturors are the same in this... with exeption of very expensive ones maybe because they don't make that big productions...)
