This is realy funny :-D! Everyone gets blinded by his own needs, considering everything else useless...
These products are wonderful, and are directed to different buyers:
The eFlash 4000 card can be used on the spare Zorro slots of the Mediator PCI. The GFX/Sound/Ethernet needs are accomplished by the PCI solutions.
On the other hand, a FlashROM/Zorro card combo is a MUST for the classic Zorro Amigas.
As for the matter of speed, this is the funniest part: whatever this is, it's not perceptible: less then a second to initialize all the ROMUpdates and the patches/drivers...
The whole thing brings to my mind the kids dispute: "mine is better than yours", "no it isn't", "yes it is!" and so forth...
