Summary: Have converted a few folks to Linux and run into this scanner model. There is absolutely NO support from Microtek and evidently, never has been and never will be. No matter its physical condition, it's junk to Linux because of lack of a simple driver.
Summary: Mikrotek is not helpful with problems. The scanning is good but it keeps loosing the connection to the scanner. No help to be had from Mikrotek. I had to repeatedly reconnect the cables and when I am in luck it decides it is connected. But a lot of the time it decides it is not connected. After two years I upgraded to Mac OS 10.8 and Microtek has discontinued drivers and won't support OS 10.7 or 10.8 so it won't work.
Summary: The i900 scanner is a great piece of equipment. I primarily need to scan medium format film and was very please with the results. The film scans were clear and sharp. The details and shadows were captured which is what i expected from a good film scanner.
Summary: I bought this scanner because I want to be able to digitize my older 35mm slides and negatives and my more recent large format work. I looked at the specs for this scanner and compared it to others of this type and found the performance to be incredible. I get the superior results I want and have the ability to scan any format I now shoot or might choose to shoot in the future.
Summary: If you're a Mac user, don't buy this scanner if you want to be able to upgrade, or if you're already running Lion. Microtek has discontinued drivers and won't support Lion, so it won't work. In fact, if I were you I'd avoid them entirely. The scanner has been fine for me, which makes it all the more frustrating that I'll have to get rid of it simply because the manufacturer refuses to support their own product. They deserve to go out of business.
Summary: The software that comes with this scanner is the weak point, it crashed numerous times. Don't use the CD, download everything from the website. It comes with a pretty complete manual, but the way this software is designed it needs it. They could spend more time explaining what they mean by a batch. Also, to have a transparency scanning area of 8 x 10 and make a carrier that holds two strips of 35mm film is crazy, what about the rest of the area?
Summary: I bought the i900 because I wanted a scanner that would do slides & negatives besides normal reflective scans. I have an old Scanmaker E6 that is still working great, so I decided on the i900 because it was cheaper than most film scanners and could do more than just film. I considered the i800 but decided against it as it seemed not to be as heavy duty with a cheaper, lighter construction and using a brick power supply rather than an internal supply like the i900.
Summary: I selected this product because I needed a new scanner and wanted one that could scan my large collection of 35mm slides as well as prints and documents. I have scanned a couple of dozen slides so far and am very pleased with the results. The color is true and the resolution allows for good detail. The software includes Adobe Photoshop Elements, which I had not used before, but I'm finding it easy to pick up.
Summary: I'm a Mac user so software problems might be different then PC. I bought this scanner in 2006. I'll tell you what you will be in for now and a year and more from now. The firewire quit functioning on the first one I got so I sent it back under warranty. The firewire quit working about a week after the warranty expired on the second and I was told I could have the scanner replaced with a refurbished one for $250. Believe me the scanner isn't worth it.
Summary: I have owned the i900 for about six weeks and I am very happy with the way it scans both negatives and regular photographs and other media. The quality of the scanner itself is excellent and coupled with PhotoShop Elements and ScanWizard Pro, it produces excellent digital files. Installation of the ScanWizard Pro software posed a few challenges but once installed it has worked perfectly.
