Hi Gilloo 
Yes the Subway is a good solution for the clockport but unfortunately it is slow and i still have power trouble with it even with a powered hub. When someone has used the Deneb, it's hard to only have a Subway in its flagship A1200.
I will have to agree on this: the subway is too slow, even in Amiga terms. The only good part of the subway, is its software...
And I am not mentioning the lack of USB 2.0 highspeed mode and the power issues.
I still think an A1200 deserves a better USB solution than the subway. The Deneb is a great solution and the spider PCI card is still miles faster than a subway anyway.
