When buying a device, which method works best for you? Should I do a needs analysis first, or compare price-performance? Or should I just follow reliable brand names? How do you guys approach this? What’s your experience? I really want to learn.
What method do you prefer when choosing a current device?

Last month, I was supposed to buy a new laptop, and it was a complete headache. The first thing I did was clarify the scenarios I’d use it for: would I just open office files, or would I do some light Photoshop work? Then I listed the hardware specs that matched each scenario. For example, if I was going to do video editing, I realized how important the graphics card was. Comparing prices and performance without doing a needs analysis is basically opening the door to wasting money. That’s what I did—I first figured out my needs, then added my budget and made the comparison.
Previously, I’d just pick a device based on “reliable brand” and end up regretting it because it didn’t fit my needs. This time, I avoided that mistake. What helped me the most was watching benchmark videos on YouTube and comparing real performance data. In the end, my priority has always been figuring out what I actually need, then finding the best balance of hardware and price to match. Honestly, doing it this way really reduces the stress of making a choice.
Absolutely, they both complement each other in fact. I think we have to start with a needs analysis—because when evaluating the balance between a device's price and performance, we need to clearly define what we actually need. For example, when I'm choosing IoT devices, I first consider whether data transfer speed or battery life is more important. For instance, low latency is critical in Edge Computing applications, whereas power consumption takes priority in a home automation system at that moment. Therefore, when comparing price-to-performance, your needs determine the basis of that comparison.
Of course, following reliable brands is important, but I see it more as a final step. First, I clarify my needs and identify the products that best fit my requirements, and then I compare price-to-performance among the reliable brands in that category. This way, I know, for example, that Raspberry Pis are cheap, but I also realize that NVIDIA Jetson is more suitable for Edge Computing. So, brand reliability ultimately acts as a filter.
