I think Apple should introduce Wireless Sync to the iPod Touch/iPhone. It would be slower, but what if Apple bumped the Wi-Fi to 802.11n? The iPod could have disabling feature for the -n part, to save battery life. Alternatively, the iPod could have dual wi-fi chipsets. Wireless sync would be good for MBA users that use the USB port for wired internet. All this was slowely typed on my 2G touch/32GB/OS 3.0.
