Basically, if you're using it on a system for leisure than productivity/workhorse, you should be more than fine. Life expectancy is 7 years with a theoretical ~275TB writing capacity to the SSD before it dies.
That's pretty scary knowing your drive will die in 7 years before even buying it
One thing to keep in mind is this is the new 840 drive, which there isn't much track record on yet. So drawing conclusions about this drive's performance and reliability based on how good the 830's were would be flawed.
Not saying it's a bad drive, just saying it's so new there isn't a long track record yet, where the 830 was a rockstar drive in terms of reliability and performance.
Supposedly the new drives are the 840 and the 840 Pro, where the standard 840 will be the more "value" oriented drive and the 840 Pro will be the "performance" drive. In that case, the 830 would probably be more closely aligned with the 840 Pro rather then the standard 840.
This loosely translates to slower 'program time' (i.e. lower write speeds), as well as lower long-term endurance of the flash memory as a whole. Cell leakage is a consequence of wear, and the same amount of leakage will cause more bit rot on TLC as it would with MLC. Samsung claims to have taken care of the endurance part of the equation with greater overprovisioning, but even so they have reduced the warranty period of the 840 down to 3-years from 5 of their 840 Pro. This review will hopefully shed light ont the first potential issue - write speeds.
I would spend additional and get an 830 when on sale. Basically TLC is trying to stuff more data is the same size memory, and thus slower (smaller con) and greatly limits the life expectancy. Also there maybe a multitude more of issues, once the drive is over 75% capacity.

It doesn't greatly limit it's life expectancy. It's simply has lower life expectancy than MLC. However, for you, as a user, it doesn't matter since you'll stop using it long before it happens.
Don't make conclusions from pseudo-technical publications written by people without any real qualifications or expertise in the matter.
