I have been getting the same message since late March: Estimated Availability NVIDIA GeForce4 Titanium Temporarily Unavailable. Check Store in April for new availability date. Is this an omen of the future? I cant see how if they cant even ship a video card yet how the G5 can be released this summer. Can apple meet the demands of the consumers? I love apple and I hope they can do it, but the message says to check back in april and april is half over.
