Hello, I have a older macbook (1.83 GHz Intel Core 2 Duo, 2GB ram, OS 10.6 ) and my 7200rpm HD just died on me. I'm wondering if I should pickup a replacement 7200rpm (or even 5200rpm) SATA HD or spend extra for an SSD. Anyone using an SSD as their OS drive in their laptop? Notice any improvements? I'm the type of user who never shuts down his laptop, so booting up speed isn't an issue as it happens so rarely. Also, I dont do much heavy work on my laptop. I will occasionally record audio in protools, but thats always to an external FW drive. The laptop is mainly used for surfing the web, for web video playback, and for appleworks. Its my understanding that SSD's make launching applications MUCH faster, but once opened, do they still show performance gains? Would an SSD make any sense for me?
