I will tell you of my experience of owning a UEMIS. First there are some who have issues with the computer and others who have not had one thing go wrong with them. Currently a couple of guys have bought the bankrupt UEMIS company and are trying to get it off the ground. With my computer I have had to have the battery replaced TWICE so far since I have owned it. I have also read posts where people have issues when taking it on a plane and it gets stuck in a dive mode. The solution to this is to have a sealed container to take it onto a plane. The second time I had the battery replaced I sent to Switzerland to the new company. It took almost 5 months to get it back and the communication with them is not very good. When they did send it back they did NOT charge the unit so when I took it out, it still did not start up. I emailed them and that is when they informed me that they do not fully charge them before shipping them out. Would have been nice if someone would have told me that. Actually the computer showed up in a package one day without any warning. They did not send an email telling me it was fixed and coming back. The one good thing so far is they said they would send me an invoice for the charges which was going to be around $175 and I have yet to get one. So as to date and I can only guess they did it for free.Unfortunately I had my transnitter for the UEMIS stolen so I cannot use the computer until I replace it. I have yet to find a place that will sell them. The UEMIS website still does not have an online store. In my honest opinion I would wait a long while to see where this company goes before you drop that kind of money.
