I notice some of the older 24" iMacs can only accept up to 4GB of RAM (The current iMacs can take 16GB to 32GB of RAM). My current laptop (in my sig) has 8GB of RAM and I think it is necessary. Is it the right choice to buy a second-hand 24" iMac even though it can only accept 4GB? I mainly use my computer for internet access 90% of the time and even though 8GB might sound like it is too much I feel on the other hand 4GB is too low. I am also planning to replace the iMac HDD with an SSD right away. Would that help with the lack of RAM? What can be said for the future? 4GB sounds a bit low now and will definitely be later on. I feel Apple made a dirty move to neuter their powerful desktop line with less RAM so it would be less future-proof and will force users dump a perfectly usable computer.
