Hi Everybody: I wanted to thank everyone who answered my question about my ti-book problems. I took your advice and bought a 512 RAM chip from Crucial, so now I have 768. It was an easy process and I got it installed today. The difference in the speed of my machine is incredible. I feel like I have a new computer. So thanks again. Do I understand that there are other speed upgrades that can be made on a ti-book? I have the 867 MHz one. Would there be any point in doing that now that the new laptops have different technology? I hate to think that in a couple of years my laptop might be quite obsolete. I had a Mac clone and it got to the point that I couldn't upgrade my OS beyond OS 9.1 without replacing the processor. At that point I chose to buy the laptop--which is my only computer. Thoughts? Another query. I have been dragging my heels over getting something to back up my data. I do burn CDs now and then, but I need something that is a bit faster and I can do every time I create a new file. I also have a flash drive and that is ok, but I have thought about having an external drive that I can schedule to backup for me without my having to remember to do it. Any recommendations? Firewire or USB? Is dot Mac worth the annual fee? I so appreciate this forum. Thank you for being here. Regards, Carole
