the congestion is indeed an issue SE has yet to address, they could easily fix it on the PC by making it a torrent, and allowing users to share it, or they could change POL Viewer to have a Torrent client in it to relieve congestion(you being able to control the bandwidth of course) also giving you the choice to save the updates for later use in case you need to reinstall, I'm sure there are solutions that could be done, I just think SE has no intention, very little about what they are planning for the future of XI is worth getting excited about at the moment
