For someone like me who is quite particular with electronic gadgets, I would prefer dell or apple computers as reliability wise, they are more proven for me since I have been using them for a long time now. When I found out that I needed to upgrade my Dell memory as not only was it obsolete at 512 MB capacity, but the programs coming out these days require RAM memory of usually minimum 1 GB. I was having a hard time coping with all the applications and games that I have installed there so I opted to upgrade. In the process of searching for that dell ram, I also tried looking for some Mac memory to upgrade my other computer as it also needed an upgrade for the longest time now. The good site I found was www.memoryupgrade.pro where they have reasonable prices for all kinds of laptop and desktop memory modules and it turns out it was a real great buy for me from this online site.
