Indeed I also think that this criticism has been rather harsh. I appreciate the noted issues with the tool (which aren't that significant for me), but it still looks far better than the Hornby offering, and is offered at a competing price.
Sure, there is still a market for a 'top of the range' model, a-la the Bachmann MK2f, but that comes with a price premium. Oxford are not offering the 'definitive model' with all the bells and whistles (and cost) so it's unfair to judge it as such.
