I'd say that's a big positive (at least for Samsung, Crucial and Intel controller SSDs, not so much for SandForce, Indilinx and JMicron). It took hundreds of terabytes written before the SSDs failed. Besides, it's an HTPC. I don't know about folks here but I don't keep irreplaceable data on my HTPC. If the SSD fails (probably after at least 2 years barring random controller failure), it's easy enough to replace it with a new one.
I recently replaced a failed OCZ Agility 2 90GB SSD (at the time, $180) with a Crucial M4 128GB SSD ($100). After 60 days of use (1,423 hours according to CrystalDiskInfo), I've used up 25 out of an estimated 3,000 PE cycles. That's approximately 3,200 GB written which translates to 53 GB/day. The SSD is the only drive on the HTPC and is used as Live TV buffer. I use a different HTPC for recorded TV. Assuming usage remains the same, it'll take around 20 years to completely run through the 128GB M4's PE cycles.
On a side note, the Intel X25-M 120GB SSD on my Windows 7 workstation has only written 2.60TB after a year and 2 month's worth of use (10,474 hours). I also have another Intel X25-M 120GB SSD used to house virtual machines (normally running 3 XP VM's at the same time) and so far, it's logged 760GB host writes after four months use (2,955 hours). That's including the occasional virtual hard disk defrag (around once every 1~2 months). Note, I don't defrag the SSD itself (that's just stupid and completely unnecessary). I only defrag the VHDs from within the client before compaction to get better compression when making backups. I used to copy the VHD to mechanical disk first and defrag the backup but the process just goes so much faster if I do the defrag and compaction on the SSD. Every time I do, though, it usually equates to 20GB of host writes per VM.
I'll quote my post from another thread regarding a similar issue (Minimum SSD size for Live TV Buffer + TV recordings

The Kingston SSDNow 40GB (rebadged Intel X25-V 40GB 34nm) appears to be crazy reliable. Even after 466TB written, it still passes the data retention test when SSDs with higher capacity using different controllers have already failed.
The Intel 320 40GB also performed beyond expectations.
You'd likely see some random controller failure before you hit the limit of NAND endurance.
