Like you, I go way back with Apple products, starting with the Apple II+. I can't think of any that were perfect on day 1, though some were close. It's both annoying and amusing how people come to this and related threads to opine that the AVP is a dud and will be canceled, as if to let those of us who are actually satisfied know they have insights we don't.We, as users, focus so much on launch products on those elements that are not perfect or fully refined. The totality of the product for my experience is amazing and worth the price of entry. Those parts that are still amazing, such as cinema mode 3D movies, but not fully refined lend to the question of return of the product, as is the discussion of this thread. The AVP may be a "dud" for you when and if you experience it because of these shortcomings. I only suggest in my postings that you not allow the strong opinions both in favor and against to sway you in your decision if you choose to experience or purchase one. This is a very personal and potentially polarizing product.
I had a mouse package on my IIgs. It allowed GUI but was clunky, unpredictable and not very useful, but I tolerated it because it was amazing and like nothing else on the market. Even the Mac 128 was a bit of a challenge but look where it took us.
I'm well aware of the AVP's current shortcomings, but it' still worth it to me for what I'm getting out of it, and I expect that to improve as more content and apps become available. Unlike the cognoscenti who are certain the AVP has already failed or will fail, I honestly don't know. And neither do they.
If you're considering an AVP or are just curious, I encourage you to try one and decide for yourself. (The demo experience is usually too short to tell, so give it at least a week.)
