Bert,
Apologies, I'm afraid I'm going to have to disagree with you.
Firstly, even if SSD drives were 10% less reliable than traditional drives (that is quite a lot and the actual number should be far less) that does not affect the overall statistical probably of failure over a 5 year lifespan between an SSD drive and traditional drive all that much. In fact, if you surveyed 100 computers with SSD drives versus 100 computers with traditional drives over a 5 year period, you may notice one more drive replacement of the SSD's versus the traditionals.
Secondly, backup, backup, backup. The cost/performance ratio of SSD's, as it continues to come into better favor, means the risk is worth it. Even at 10%.
Take a look at this article from Tom's Hardware:
