I just wanted to share with you guys the upgrades I've recently done with my macbook. I have the mid-2010 basic 13" model (2.4 Ghz, 4GB RAM). Not wisely, when I got it, I've installed an entire Time Machine backup of my iMac. It was a mistake, I should have done a clean install and just migrate my settings. It wasn't so fast from the beginning, and as time went by, and lion was installed, it just became worse. I knew I had to do a clean install, so I decided to upgrade the mac as well, and to do it in separate steps, so I'll know the impact of each step. The first thing I did, was to install 8GB of RAM. The installation is quite easy, and there are good instructions in Apple's website. It was also the first time I've opened my macbook, and was quite amazed to see how nice, tidy and clean it was inside. The performance boost was felt instantly. Apps launched a bit faster, parallels was working much better, and all around the mac just felt better and more responsive. Still, boot up time was very slow, and handling large files took a lot of time. Second step - clean install. Another significant performance boost. I should have done it from the beginning. Now, it felt like a mac should feel. but that wasn't enough for me. I wanted an upgrade that would put my mac at least on par with the current MBAs. Third step - SSD. I bought a 256GB Crucial M4, replaced the current HDD, and did a clean install again. I've also enabled TRIM for it. Yet another performance boost. Now, boot up time is extremely fast. launching apps, handling big files, iPhoto, iMovie are all much faster. Parallels is a joy to use. A great upgrade, no doubt. Conclusion - My 2 yo. macbook, is now faster than any MBA, and most MPB that are currently sold. Sure, I payed for the upgrade, but it's totally worth it. I have no doubt that it would serve me well for at least another 2 years.
