Hello Ellen
You may want to spend some time on the FOG - Festool Owners Group forum for tips and tricks. Many professionals who are heavily invested into the brand. Sure there are some fanboys but for the most part you will get honest feedback and like Shane said earlier, Festool does monitor the forum.
I have the Midi - a Mini with a slightly larger bag capacity, as well as the larger CT22 with the boom arm. As to the hose, I have never had issues hooking up to any of my sanders as long as I push it on a couple inches or more. It is a very snug fit and can be hard to get the hose end on the sander. The Festool regular hose - not the supplied anti-static one - is far more flexible. Also you can go to either of the big box stores and their hoses fit the Festool vacs just fine for very low cost if you would like the larger diameter hose. I have done that. I agree with others that the hose garage is kind of a pain - should be an inch or so deeper. And yes some of the sanders might benefit from having a flatter top to ease paper changing. I agree that an upright handle would be nice at times. The cord issue I guess is a result of our 120volt system in the US versus the 240volt system in Europe where they can get by with a much lighter smaller power cord and again I agree with you that a simple hose wrap would be nice. I don't use the top garage at all but my Midi stays put most of the time.
The thing with Festool as they say is the system. I never understood that until I ended up owning much of what they sell. Now it is very frustrating to go use other big name tools as they just don't work together like you get used to with Festool. Obviously you can achieve the same results with other brands for less investment. For people who appreciate quality stuff and don't like to be frustrated when using tools, Festool as well as a couple other premium high dollar brands have much to offer.
