After trying a cheaper docking station / DAB radio from a supermarket which I ended up returning, this Sony is much more impressive. There was no interference from the phone, and the range of DAB stations that it was able to pick up was much improved. Some over 50 miles away from where I live. The features are good, and most importantly, the looks, sound quality and build quality appear good enough to last a few years.
Set up is simple, plug in, it sets the clock and scans for DAB stations. Has 2 DAB tuners. Alarm setting is simple, with setting for 2 alarms, e.g. weekdays / weekends. Comes with a battery for handling electrical power outages (mainly so the alarm still goes off, not for holding the clock time as that is set from the DAB stations). Sound quality from iphone 4 is good, charges the iphone of course.
One downside is the remote. Its small, but the buttons are all the same size, and little to tell in a dim bedroom light what they actually do. However, I guess with time that will be less of an issue.
(Getting hold of these is difficult at current time of writing this (Jan 2011). Ours came direct from Sony, I didn't want to wait 1-3 months. That's a first for me to not get direct from Amazon, perhaps proving the popularity of the product.)
Overall, a good product.
