iRadio? Hasn't even launched, already irrelevant because there are far better services out there which offer more control + social capabilities.
Mavericks isn't really amazing. Missed opportunity there.
rMBP? Underpowered and not ready for prime-time.
Real AppleTV? That's Bigfoot.
I agree on some points, but others are a bit dramatic. I personally own a rMBP (13") and could never move to another (lower resolution) laptop. Being able to switch from 1280x800 while browsing to 1680x1050 for working and still have everything be pin sharp is amazing. Do note I write code most of the day, but I also use it for light video editing and Photoshop.
Mavericks is also a huge step up if you use multiple monitors like me. Also finder tabs (I end up having 5-6 finder windows open at all times, super cluttered for expose.) The behind the scenes features are quite amazing as well and should provide even better battery life/efficiency for older hardware (That supports it, of course

)
iRadio is actually quite good, and will be putting Pandora out of business. Sure it doesn't compete with Rdio/Spotify but it is way cheaper for those who just want to put on a radio station and not mess around with playlists all day (Disclaimer: I subscribe to Rdio.)
The Apple TV is so close to being a really great product - the hardware has everything it needs, but it will require a huge software overhaul. Keep airplay as it is the primary selling point of the device right now. Integrate controls with iOS - I don't want to have to search for the Remote app on my phone.
The biggest feature they need: Allow Siri on people's iOS devices to interface with the living room apple TV. I should be able to search all available content on the device just using my iPhone's siri implementation, and then be able to play it without touching a device.
I think the main issue is that the board/analysts are looking for the next big hardware advance from Apple and they have been stagnant there. The iPad was introduced just 3 years ago, so judging on their past product launches they are coming due for a new category. The question is whether it will be another iPad level success or a Rokr level failure.
