TomTom have been market leaders in simplicity and accuracy of navigation for many years now, and I have been a loyal follower having used several models. The new 1000 / 1005 series (1005 simply has a bigger screen), is another step forward in the device - slim, attractive and so easy to use. However, there have been a number of criticisms of these models as TomTom seem to be reducing functionality rather than increasing it - so, for example, you won't yet find the ability to add your own POIs, btu the company says that is coming.
What you have here though is a continued refinement of the core functionality of the device - the ability to go from A to B simply, easily, with the minimal hassle and without getting lost, ending up in a dead end, or the wrong side of the country! The TomTom 1005 does that superbly. The box arrived just before I had to make a trip to Shropshire, via the M5 / M6 junction, the satnav was out of the box, in the car, fired up and ready to go within minutes - it is very intuitive. It comes with a year of 'live' services free (payment after that) and they are very good - accurately predicting each set of road works / traffic jams.
The new mount is also very good - drop the satnav on it and magnets pull it into place - when you are ready to go, just pull it off...
So, yes, there is some reduction in what it can do - if you want your satnav to act as a multi-functional, do everything in the car type of device, then perhaps one of the slightly older models will be more suitable, or await a later stage in the life of this model, however if you want the latest iteration and just need to get from A to B then it is very good - 4 stars only because it seems strange for devices to go backwards in functionality!
