I always hated having to shop for more memory, especially for laptops. I remember having to do that once and the one I bought ended up not working for my laptop, so after that, I had to stick to my own brand. What I mean by that is… for example, say you have a Dell computer/laptop, in order to upgrade more memory, you’d want to buy dell memory, right? So for me, I had to look at the memory that was already in use and buy the exact same brand to make sure it would work. It’s a hassle, but I had to make sure.
