For someone who is tech averse, the value of a power meter isn't likely to offset the cost. Power data is an incredibly useful tool for structured training, but it doesn't sound like that's what the OP is looking for. It can be useful for unstructured rides, but not without detailed analysis. Instantaneous power numbers don't mean much, it's sustained power over time that gives you an indicator of your fitness. That's not something you can easily assess in real time while riding. Average power isn't much more meaningful than average speed (especially if you frequently train the same route). So if the idea of studying power histograms, critical power charts, training stress graphs, etc. makes your eyes glaze over, a power meter is not a good investment.
