It's a good name but I actually think Flatscreen.TV would be more desirable IMO, but even then the name would've been worth more 5-10 years ago when "Flatscreen TVs" were something new and becoming affordable. Now it's the standard/norm, so it's a little redundant to mention it's a flatscreen in 2015, all TVs are flatscreen, "Flat" doesn't help the argument.
High $xxx, low $xxx IMO. Retail/electronics stores aren't known to be big spenders with domain acquisitions.
