Best o' Macworld
I think Time Capsule is going to be the sleeper product when folks look back. My understanding is it not only provides wireless backup, it can also serve out data and act as a wireless router. Combined with the computer and Apple TV, it can be a kind of data/entertainment hub for your home. I'm very much look looking forward to getting one in February. I've dreamed of a wireless disk solution for a long time, because I have wires going every which way from my old (but still working great on Leopard!) iBook.
Not even Apple can come out with an iPhone every year. I think it was a good MacWorld with some fine products. I too wish the MB Air had been a tablet form factor, but, let's face it, most people still use regular laptops. On a recent visit to Micro Center, the entire laptop section only had two nontraditional models--the Q1 Ultra, and some underpowered tablet from HP. I'm not sure Apple can justify the R&D that goes into a tablet in terms of the outlook for future sales.
Also, movie rentals over the air could potentially rock pretty hard. I mean, it may not be Blu-ray quality, quite, but I hear it is good, and you have that instant gratification factor as well.
