Fryman,
Unless you're also using something like Windows Media Player to manage content on the device I would stick with MSC. The current MTP plugin is a first draft. It should work with the e280 because that is the device I used in the development process. However, it's slower than MSC and more likely to have problems. It turned out to be quite difficult to do. So that's why I'd advice that unless you need to have the device in MTP mode, stick with MSC.
Regards,
Will
