Re: I had not heard of Tizen before
If they do insist on using then the hackers will find a nice fat juicy target waiting for them.
If they are serious about ditching Android and going with Tizen in the competition with iOS (in all its guises) then Samsung need to spend all that mega profit that they are making on it before it can be considered a serious contender. Unfortunately, we'll probably see more devices using Tizen before it is ready.
Yes, the same can be said for both iOS and Android at the start but I think the gadget buying public have moved on a bit since then. If these devices turn out to be crap then Samsung will have to take the hit.
For me it is just another reason to avoid Samsung when considering a purchase.
