Well, I understand your recommendation, Kappy, but what's to say about Time Capsule? Apple hasn't issued anything yet that sorts out the malfunctioning of this product with the Time Machine, under Snow Leopard!!!
It doesn't look like you understand drivers or the lack of drivers at all. They don't come from Apple unless Apple designs the product. You'll know when the Time Capsule is really dead because Apple will say so. Until then, there will be drivers and continued development. It might take longer than a month. Legitimate bugs do happen.
There is quite a difference when a company says it supports a product (Apple does support Time Capsule) and a company that doesn't support a product at all (Agfa has not released drivers or updates for 8 years).
In the first case, you go to the vendor (Apple) and download updates or complain to tech support that your product doesn't work. You will probably either get new drivers or instructions or resolve an issue through troubleshooting techniques. If there are problems with a driver from Apple for a product they say they support you will get some help. Just like you can forget about drivers for a PPC Mac that Apple is not going to support with Snow Leopard, Apple said that up front.
With an Agfa scanner you were not told that the product is designed for Snow Leopard but you bought SL anyway. Agfa has not provided any support and apparently doesn't plan to. Apple can't make Agfa do anything to help support their product. It's dead from here on out. I'd guess that the small number of these scanners still in use doesn't help get new drivers. Vendors upgrade products they make a profit on, or to ensure customer goodwill for future purchases. Agfa doesn't care if your scanner doesn't work, and hasn't for many years.
Some HP Printers are not getting new drivers. Apple makes the platform, vendors design products that work on it, and usually they upgrade their product drivers for new OS's. The very same driver problems were part of the Vista melt down. I don't enjoy any version of Windows, but a large part of the early problems were that vendors didn't support their products with a new OS and people wanted to keep using hardware that was never designed for Vista.
This shouldn't come as a surprise to you. Review sites on the Internet that have described Snow Leopard's improvements have mentioned the architectural changes that might require new drivers for older hardware. Apple said there would be many issues with older drivers and that many companies would have to upgrade their programs and drivers to work well or even work at all. Apple's been saying this for over a year. Vendors have had access to the changes for 3 or 4 months. Some vendors cared and have been quick with upgrades (Brother), others are just late (HP, Canon, Epson, Western Digital), some won't come at all (Agfa, Buffalo).
Hardware upgrades have been a fact and expense of OS changes since the mouse. I was really not happy when Apple dropped ADB ports and my expensive trackballs and art tablets needed pricey USB to ADB adapters for Jaguar. I was really not happy when the adapters quit working with Tiger, apparently because the USB adapters couldn't provide the ADB drivers required that Apple finally removed from the new OS... We could have gone back to earlier OS's, but that's never been the way.
