There will still be a slew of this version that people have. If someone gets a V 2, the V 1 can go in the field day kit.
What really matters is software which makes full use of the capabilities of either model, user documentation, etc.
edy555 and hugen79 have provided us with a very nice instrument which almost any radio amateur can afford. There are a lot of better units, but this one is about $35 delivered from China. My xaVNA, VNWA and 8753B cost many times more.
Things like python scripts which test RF connectors across all the ham bands or other ranges and compute statistics about uniformity, losses, etc have long term value. Most of the work is in creating a good presentation of the information.
And if, like me, you have no experience using a VNA, the nanoVNA is an excellent learning tool. Set yourself a task such as testing feedlines and antennas and figure out how to do it so that it is entirely in the nanoVNA FW. Treat it as a device with a changeable personality and develop different personalities for different use cases. But most of all.....
Have Fun!
