Some good stuff, some bad stuff so lets see if we can break it down.
- Mainly good.
Thinner iTouch, smaller Apple TV - reduction in size is always good as it eggs on the industry to do the same, advancing the art of the possible.
iTunes 10 interface - album art instead of the same album name droning down the screen, looks a lot nicer.
- Mainly bad.
Apple TV - being objective it doesn't matter if it is cast down the internet or if it's a cable TV service like HBO, you have a set-top box and can watch TV shows or films. Charging model should be the same with a flat monthly fee and as many TV shows as you want unless it is premium stuff like sporting events or brand new TV shows, but if I want to watch re-runs of Star Trek that are syndicated on free to air TV station then that 99c is ridiculous.
New Nano shape - Again fudging with the shape so anyone who has a pouch, holder, accessories has to buy them again to fit. Joggers with the neoprene armband will be livid. It honestly did not need to shrink, a more natural progression would have been to follow other Apple products and make it a mini-iTouch, same form-factor but touch screen. Yes, they did the screen already, but fudging the form-factor was just nasty, expect next years revision to put the form-factor back to what it was with a touch screen just to force everyone to buy the accessories yet again for a 4th time.
Social networking - Why, just why. Expect Jobs to tear into Facebook the same way he was with Adobe over Flash and lots of bitter feeling all round.
