Need an Upgrade?

Remember my Macau holiday with some girlfriends? I took quite a lot of photos on my digital camera which I've already transferred to my laptop. So last Saturday, one of my girlfriends came over to copy the digital photos to her flash disk. I turned on my laptop, and it took a loooooooong time to start up. I was told that it is time to upgrade my laptop memory to a higher ram. Is slow start-up a good indication for an upgrade?
