It looks like Dell's ran into issues with its highest end monitor, the scrumptious DisplayPort-packing 30-inch 3008WFP.
Engadget heard it'd mysteriously vanished from the site with nary a trace, so we pinged the folks in Round Rock. This is what they had to say:
"The Dell 3008 monitor has been well received since launch and has been very popular with customers. In February we experienced a small technical issue with the product that has been long resolved. [Um, it's only April? -Ed.] Currently the monitors are on extended lead times and in order to manage demand, the 3008 is not available on dell.com. We are managing orders on a prioritized basis and hope to have the product available to all customers in the near future."
So there you go, down but not out. Expect 'em back, um, eventually.
