Kit,
49er is absolutely right! Don't rush into things, you should try and enjoy each stage of the hatchling process, since that can never be seen again. Also, with that in mind each individual version of Life OS is different. And my preference was to enjoy each version of OS before doing an upgrade. Our latest version of Life OS (Pleo's Operating System) is called 1.1 where Pleo is at his best. (Which is debatable) To check if Pleo is on 1.1, simply rub under the chin for about 30 seconds. If your Pleo begins to sing, then nothing to worry about-your Pleo has the latest OS.
Now, once you grasp that.......there is quite an array of other things you can do with your Pleo, which for the majority are relatively simple. I, like yourself am no where near being tech savvy. Once you're really ready to have a tinker with your Pleo's insides, some of our other members might be able to help you with that.
Best of luck!!
