We have an M1400 that has been giving us trouble for quite some time now. When in the cradle, when you try to adjust the video settings or switch to multiple monitor mode the tablet crashes. We have sent the tablet in numerous times to get this fixed, but it seems that it cannot be reproduced by Motion Computing so they cannot fix it. We have another tablet of the same model that does not have this problem and we know that it is not specific to the cradle because of testing. The support there is poor. They promise you a great deal and do not deliver on any of it. When we first ordered three tablets from them, the charge for the tablets was immediate on our credit card and we were told no more than 2-3 three weeks for delivery. Two of them took more than six weeks and one took nine weeks. Though we did not have the equipment they had our money. But this is normal operating for Motion Computing. If you send in a tablet for repair or troubleshooting, they will promise a quick turnaround. Do not believe them because they will not deliver on time. Don't expect them to be very concerned with any deadline you have to meet that they are blowing away. I cannot speak for the quality of the product as two tablets did seem to work fine. But now we have a tablet that does not work for what we got it for and no solution to the issue. We have sent it in three times and this has taken months to do given the slow turnaround that they promise they will not have. Anyway, Motion Computing is probably not the best choice out there for your money.
