Reading the FW subreddit, a lot of said 'just drop in an Intel wifi card instead.' Well, yeah, that would surely have worked, but, again, I had already paid a lot for the machine itself. Battery life was subpar for it to be of much use as a laptop, but I didn't really mind. The screen was quite okay.
But what really put me off was how HOT and, consequently, LOUD it would get by merely watching YouTube at 1080p. Hot means really uncomfortable to touch and definitely not something you'd want sitting on your lap. People heard the fan from another room more than 10 meters away. That's when I decided that the little fan inside it would never be enough. With proper cooling, it would've been great as a workstation, though not as laptop meant to be carried.
tl;dr FW has a lot to work on noise, cooling and battery life. I don't suppose there will ever be a huge market willing to overlook these aspects just for the sake of repairability.
