I find the DE1+ to be compelling, but I couldn't imagine purchasing one for a few years. My last machine was a Silvia and when I sold it, it was old enough to drive. My current machine is an Appartamento, purchased in no small part because it seemed easy to service and relatively simple. I expect this machine to last quite some time, too, in my hands or someone else's.
The features the DE1+ offers on a consumer level... don't really exist elsewhere. On its own, that's more than enough reason to be excited. While, like some others have hinted, I don't find it to be a terribly attractive machine, mainly because I expect my espresso machines to be E-61 heads swathed in stainless, an outdated thought on its own. My main concern is longevity, both of the unit and the brand itself. I'll continue eagerly watching these threads, as everything you can do with this machine seems outstanding, but the concept of spending $2,500 on a machine that may not last the distance is more than lightly concerning.
