Miele:
Actually Miele didn't do that because of the space. Miele frontloaders are 45cm wide while a lot of other toploaders are only 40cm. The reason Miele did this because they thought it was a better to have bearings on one side because bearings on two sides give double the risk of bearing problems. Besides that, if one of the bearings goes bad and the drum might get damaged because it is still attached on the other side too. BTW, the Miele bearings are similar to car bearings, sort of overkill so you don't need more than one.
Dryers:
Several brands make 45cm wide dryers, but AFAIK there is no 40cm wide dryer. IIRC Candy never made a dryer with a width of 40cm, but I could be wrong there. At the moment they don't sell any topload dryers at all anymore. I guess they leave that to the French.
Porthole:
In the past the drum openings of H-axis toploaders was indeed rather small. Newer models give a better access to the drum. My mother has a rather new Zanker (Electrolux) that has a much bigger opening than for instance my older Philips toploader. Miele has the best solution in this matter I guess. Not only a good opening, but also very easy access with the slanted front. Sort of a mix between a frontloader and a toploader.
Window:
Many French toploaders had windows. While it is true you couldn't see the laundry, there was the possibility to keep an eye on the amount of suds.
Popularity:
I guess the Ha-xis toploader is more popular in France than in any other country. They always did quite well overthere. I remember an old Thomson-Brandt brochure that showed more toploaders than frontloaders.
If you like toploaders you must look at the website of one of our French members. He has quite a collection and also on his website there are weekly pictures. Here is the link. Look at "L'image de la semaine"! Wonderful ads and pictures!
