Just received my Gazelle Professional today. It seems to suffer from the same problems I have with Ubuntu in the past -- wireless that slows to a crawl, or even times out.
Every other machine in the house is able to connect at fast speeds (Debian laptop, Android, iOS, iMacs, Windows boxes...). But the Gazelle freaks out when it has to buffer a Youtube video. Downloading an Ubuntu iso took ~8 minutes on an old MacBook, but wanted 8 hours on the Gazelle.
