The Slide And Negative To Digital Picture Converter. at Hammacher Schlemmer

Here's the skinny, as far as I can tell from hunting around. These slide converters are made by one company, VuPoint Solutions, for various resellers/suppliers - Brookstone (under the Veho name), Hammacher Schlemmer, Frontgate, Summit, ThinkGeek, etc.:

VuPoint makes it clear they sell it through resellers... The only one I am not sure about is the Veho from Brookstone - though almost all of the specs are the same and it looks exactly the same save the Veho logo, it is the only one that works with Vista and costs $30 more ($129 vs. $99)

I found reviews of it in several different places, I think all positive:

Of note - The slide converter businesses that "Scan your negatives/slides for you" seem to charge in the neighborhood of $0.25 to $0.50 per slide (25 to 45 cents), which means that this device would pay out in as little as 200 slides for the XP compatible device for ~$100, if the quality is comparable. And it produces a jpg file that you can read with anything.

Lastly, about quality? One of the businesses that claims to be the best at this says they deliver 2000 DPI vs. 1829 DPI for this machine. I am not an expert on Megapixels and DPI's, but from reading (and from other reviews), people seem satisfied with the quality thus far.

I am about to take the plunge to scan all my dad's old slides, and we'll see how it goes! I am going to get the Vista compatible model from Brookstone, as I am sure my next computer will have Vista (fortunately or unfortunately).

How long does it take to scan a 35mm color slide?
Is the result a jpg file?
Does the resultant digital file require any computer based post processing?
Can the digital file produced be read by any off-the-shelf product? product?
