Definitely not. If I think of all of the money I've saved from not buying them over the years, it pays for an entire console replacement if I need one eventually.
I've only had one Nintendo system break on me, ever, and it was the cheapest one they ever built. I think the Switch is much more thoughtfully constructed than the Wii.
Also when it broke, Nintendo was quick to step up and fix it. Best customer service of any company I've had to deal with.
I think my drive may have been starting to fail- It was making awful noises and started freezing in places whilst playing Radiant Dawn. Then it locked up completely and I disconnected it in terror.
Thankfully the WiiU was out by then so I did the system transfer I'd been putting off. No biggie. Boxed the Wii up and pulled the Gamecube out and all was well.
With my luck, it'd crap out in two years and one day.
No.
That being said, for the people who plan on playing it away from home, it could be worthwhile, but I imagine the 3DS still being relevant for a while yet to really phase it out in favor of a new portable device. Unless you just don't have a 3DS, in which case it could be worth it.
