To be fair, the issue is probably not going to be as evident downtown. Go over to the east side in old fourth ward or inman park and I think you'd have come to a different conclusion.
Honestly I've loved mine, but its definitely not for everyone. The standard software is pretty lacking, and the cloud features are meh. If you're willing to apply the DDVK patches, and an additional launcher it becomes a joy to use. Koreader for reading, regular software for writing is a joy. Oxide is a great launcher for easily switching apps. You can setup syncthing via ssh. The hardware is great, and having ssh access was what sold me on it.
I mean that sounds like problems with one wifi card which can be swapped out for about $30. Swap it out for something like the ax200 and I bet those problems go away
