It sends an alert to your registered email , if you monitor that email on multiple devices you will see the alert multiple times..Yes, Google sends alerts to the laptop and the phone AND the tablet, every time I sign in! Can't remember what it says that sounds like the tablet is an iPad. But it works very nicely, considering it's about four years old.
Don't understand the reference to an iPad.
Don't worry about being 4 years old, unless you are interested in a feature that was not available 4 years ago and which it does not support, it's probably just a bit slower.
