A buddy of mine brought his Mini over complaining of slowness. He was going to take it to Staples for some kind of $39.99 diagnostic. Hahaha. Anyhow, he has a previous gen Mac Mini w/ 1GB DDR3 that can be upgraded to 8GB. I checked everything else out looked fine. He says it is mostly on the Internet with multi-tabs, hence my rec to get more memory. Crucial has 8GB for $45 and I was going to install for him and then looked on-line and noticed it wan't very user friendly to do so. The local Mac shop wanted $150 to do it. Seems a bit steep. Anybody else pay to have the memory upgraded? How much did it run you?
