Forgive me for being 'that guy', but I tell everyone this so they know the full picture before deciding to buy a laptop. This comes form personal experience of owning a gaming laptop
- Laptops, generally speaking, are a lot more expensive than the PC equivalent
- Finding replacement parts for them can be a absolute bitch depending on what you're trying to replace, especially the older the laptop is
- If you do find a part, or a place that has / can get the part its usually going to be a LOT more expensive than repairing a desktop. Sometimes its better to just get a whole new laptop than to repair it
- If the video card goes out, most video cards are soldered onto the laptop's motherboard requiring either a whole new motherboard, or a repair place that can (very expensively) replace the video card. Assuming a replacement can be found to begin with
- Most laptops can't be upgraded outside of maybe RAM and a bigger hard drive, while with a desktop you can upgrade things as needed
- Things like replacing a screen or a keyboard can also potentially cost quite a bit, to the point where you may just be better off buying a whole new laptop
- If you don't want to fry your laptop you have to blow it out with compressed air much more frequently due to how compact the laptop is on the inside, making it a lot easier for dust to clog up air flow.
I'm not saying don't buy a laptop. Rather just make sure to keep in mind the downsides before buying. Desktops lack portability but they have the potential to last you much longer due to the ease and cheapness of repairing them compared to laptops, and parts are extremely easy to get for them. And you can upgrade everything in a desktop.
