I can't agree more. One of the most annoying things I gripe about my quite-recent TV is that when I turn it on it says "please wait". No, it's a TV and it needs to be on virtually instantly. It's not like it has electronics that need to "warm up". It's just a slow software + hardware combination.
This is not to mention that some TVs I've seen are slow to respond to user commands because of slow software. Next time you press the remote to change the channel, think about the delay between your press and the TV registering the request, let alone changing the channel.
Let's not forget that computers take a while to boot up too. However, at least the industry understands that turning on machines should not take long and they're trying to shorten it. Ubuntu and Apple come to mind. Even Microsoft has made noises about this, and some CES 2011 gadgets I've read about mention it too.
