I'm somewhat new to the mini in my signature, coming from a C2D MBP with 8GB of RAM. I've started to notice that when I get home from work and wake it up, it's very sluggish, almost unresponsive. Opening Chrome takes minutes, reading emails is terrible, and I sometimes can't click on things in Safari. I'm sure I need to upgrade. I have 4 GB of RAM and a 5400rpm HDD. I guess what I'm asking is which should I upgrade first? Or what's causing it? I checked Activity Monitor and Memory and CPU usage looked fine. I'm also moving back home with my mom (transferred for work, planning to stay here a while and save money). Because of this, I'm a little tempted to sell the mini and get a MBP. If this is the case, I may not bother with upgrading, especially if it's the non-upgradable hardware. I'm thinking this may not be the case since it's fine after about 10 minutes.
