When your hands get sweaty, holding onto a Wiimote is about the same as trying to hold onto a stick of butter while wildly swinging your arm around. So, to answer your question: "Is the strap really necessary?" Only if you don't want your Wiimote to fly out of your hand and crash into your TV screen, lamp, Wii console, bedroom wall, etc.
A. Shipovsky stop being mean and stupid, the Wrist strap doesn't get in the way while playing, and why are you trying to say that we have sweat on our hands more than you do? Oh yeah and I think the wrist strap is really neccassary, I mean think of the things the could happen, broken HDTVs, Broken bones, a Wii-Mote lodged in your head, or even worse your pet getting killed by a Wii-Mote O_O!
You asked if we think the strap is necessary and you've got your answer. Many of us do. My wiimote just flew out of my hand and got dangerously close to my flat screen today during a game of Wii tennis with 2 other friends. In order to avoid knocking each other out, we had to stand with plenty of room between us and as a result I was right next to the coffee table. The wiimote hit the coffee table during a swing and flew out of my hand. It wouldn't have happened if I had remember to put on the strap. Bummer...
I personally know someone that happened to... Their kid didn't want to wear the strap, and accidentally threw the remote into their *new* plasma TV. While I don't think it's as likely to happen with an adult holding the remote, it's not a chance I would take.
Definitely needed for kids since they are usually over active and careless. I rarely use it but I am 15 feet from the TV and have lots of practice using my PS3 controller (which has no straps.. which I wish it did for bowling). On the other hand, if it is sports related, I make sure to use the strap just in case. Most of my Wii games have little movement and the wonderful glove that came with it keeps it from slipping. I make sure to use the strap for any throwing game where a person might let go of the control (baseball bat, bowling ball, golf, etc.).
There's an option of having the strap on or off, but it just provides more stability within the hands. Lowers the chances of an accident happening as well. No one would like their $35 dollar wii remote busting on a wall or damaging other items/people because of a slip of the hand. Some games require you to "swing" the remote really good too, just like the wii-mini games that come with the system (bowling).
LOL! Like a projectile missile, someone has to swing that remote pretty hard and fast for someone to end up with broken bones. As for flat-screens it depends on what you have, if it's a plastic cover it might leave a dent, if it's glass, the wii-remote might "bust" if thrown hard and may leave a mark/crack on the tv. Apparently everyone is playing with *New* flatpanel tv's nowadays with a wii remote. I, on the other hand, am fine with a glass-panel flatscreen.
Well, in certain games like Wii Sports Resort, Warioware, and Grand Slam Tennis you can easily drop the wii remote doing the motions the games require. Besides safety, dropping a wiimote from high up could break it. I suggest wearing the wrist strap always, like I do, because I have just gotten used to it being there.
Why would you take the risk of NOT wearing it? You don't even know it is there until you go to put downthe remote. From a personal experience, my 4 year old daughter and 80 year old grandmother let go just about every time they bowl...my $3500 HD is safe because of the nifty little strap.
They put the strap on there so they won't get sued. If someone accidentally flings their wiimote into their expensive tv and breaks it, Nintendo has the defense of saying, "Well, it's not our fault you didn't use the wrist strap". Plus, it can be removed.
