If it turns out similar to the OnePlus One then it will be competitive for at least two years. That may sound unrealistic but I’m basing this off of two things:
The OnePlus One was a great phone that lasted in quality and performance for its first two years. It didn’t show signs of age until after its second year. It had a smooth OS, the best battery life, no boost ware, decent camera for the time, good screen for the time, great build quality, and the bells and whistles (NFC, Bluetooth, and customization from CyanogenMod).
The V is in a similar situation. It has competitive specs in all departments, and near the top in some. Great Battery life (soon to be conformed), great screen, ntrig pen, quad speaker and dac, usb c.
But the key thing is that these two products came out with great prices. That’s what kept them competitive even after they weren’t the newest devices.
Laptops tend to age better than cellphones. And while they don’t retain their value well they still retain their usefulness.
Laptops, well at least decent laptops, tend to be fluid and with few flaws for at least two years. After that they begin to slow and show age but remain usable for at least 2 more years. You can always find uses for old laptops, whether as a YouTube player in the kitchen or server for Minecraft.
Products like the V that come to market with top specs at low prices are naturally better values and in rare cases like the Oneplus One and soon the V they actually have top quality and long device life. Add on to that the benefits of being a laptop, which don’t age as bad as cellphones, you don’t really have to worry about the V becoming obsolete soon or even later down the line.
But then again I’m biased as I have a really old laptop and down really complain that much about my devices but rather live with their problems.
