Mbox Micro Cost Justification

It seems to me that the Mbox Micro is a great idea. However at first I had trouble justifying the price for a so called sound card when it does not include any audio inputs only the 1/8th jack output.
For a full review on the technical aspects of the Mbox Micro check out http://www.proaudioreview.com/article/16592.
So lets do the maths.
An Mbox 2 Mini will set you back around £185 for this you get an audio interface that can handle two simultaneous analogue inputs and outputs. One XLR analogue input for connecting a microphone and two 1/4 inch jack line-/instrument-level (DI) analogue inputs for connecting guitars, basses, keyboards, synthesizers, drum machines, and more.
Purchasing any new Mbox 2 will provide you with the new Pro Tools 8 update. Which would normally set you back £106 for a downloadable upgrade.
Now looking back at the Mbox Micro for £144.
£185 (Mbox2 Mini)- £144(Mbox Micro)=£41 difference.
So yes you are paying £41 less for the Micro however you still are losing out on a lot of the recording features of the Mini. So in this sense for what the Micro is it seems overpriced to me.
However if you are already a Pro Tools user and have not already upgraded to Pro Tools 8 then buying the Micro is a great way to get a packaged copy of Pro Tools 8 and then the Micro works out cheaper.
Lets say you might pay £115 for a DVD copy of PT 8 then you are only really paying £39 for the Micro itself. This now sounds like a much better deal. Not to mention the advantages of having a hard copy of Pro Tools on disk. It is a rather large download so the DVD defiantly made installation quicker.
