I remember complaints about the Leaf Desk being a proprietary system. Is that a problem with AP Server?
No. The Leaf Desk was a single-purpose device. Its hardware and software were designed especially to receive and manage pictures. That made the Leaf Desk very efficient and kept its cost much lower than off-the-shelf computers with comparable image handling capabilities. But it also meant that upgrades, support, repairs and interfaces to other systems could only come from one source. By contrast, AP Server uses standard NT server hardware and operating system.
