Who here agrees that if someone owns an A1200 that he should never buy this? Why? Well, simply put A1200 already have an IDE port inside the motherboard....second...you lose your PCMCIA for a harddrive that could have being used for something more important than a harddrive.
Though....it does look sexy and elegant...it is a useless device. Unless people want to mimic Amiga 500 but with AGA capacity and does not mind their Amiga have no access to the internet.
You can put two IDE devices into the a1200 internal IDE, its too easy... if you uses the PCMCIA port with external harddisk, sample or whatever you cant use it with another PCMCIA at the same time, your post is a bit empty.
