Old Nexus 7 still worth it at 179.99 (Compared to New Nexus 7 at 249.99)?

The old Nexus 7 (2012) is on sale right now (16GB), and it's a pretty big difference in price from the new Nexus 7. But with the NVIDIA processor, and flash memory lifespan issues, is it still worth it? I know TRIM in 4.3 was supposed to fix the latter issue (did it, for anyone who has it??), so I'm probably less worried about that than the integrity of the NVIDIA processor.

My main usages will be PDF/book reading, using social networks, and other productivity stuff. 99% no gaming.
