Here's the drawback so far, I cannot upgrade to the Windows 10 Insider Preview. The reason is that in order for Windows 8.1 to be installed on a tablet like this, the OS had to be compressed. When trying to upgrade, the compressed Operating System tries to move to a Windows.old folder and leaves no room for the new OS to be installed uncompressed. Rest assured, Microsoft is working on it, the company seems to be really reaching out to the users, taking the feedback from the Insider Program to make the finest quality product possible.
