I just bought a Calypso, mainly due to this thread. I'd been thinking about getting one for several months, but Tommi's advice and Ewok's pic finally convinced me.
One reason I was kind of hesitant to buy one is that I was under the impression that the blade is essentially a wharncliffe, with a completely straight edge. It's not though. The edge certainly doesn't have a lot of belly, but Ewok's pic clearly shows that it has some curve, which made it more appealing to me.
Also, everything that Tommi wrote is accurate. It may sound exaggerated, but it really isn't. I would only add that you should try to fondle it yourself. In pictures, it may look a bit boring and unremarkable, but when you see it in person, it's simplicity seems much more elegant and refined.
