so what is an ipad; is that like a chromebook.
No.
An iPad is basically a large smartphone that doesn't make calls.
They are touchscreen, although you can add a keyboard, and tend to have a lot less storage than a laptop - they aren't really intended to have files stored on them, although it is possible to do so. They are great for surfing and watching TV/film, and ok as music players, but are basically expensive toys.
A laptop is more of a work-based item. You can store enormous quantities of files on them, and they can cope with power and data-hungry applications. You can also store files in the cloud as back up, but you can keep them on the hard disk so they are more secure. You also download your own applications to it. They vary in price.
A Chromebook is a laptop with no storage, so you can't save anything to it, and can only use it to access the Internet. If you go out of range it is useless (as my daughter found when I bought her one for university). You have to use Applications which are online, too, as you can't download your own. The advantage is that they are cheap.
Which is best for an individual really depends on what they use it for. If you don't need to keep files private, don't need apps which are not available online, and are always in wifi range (ie don't need to use your computer out of the house) then a Chromebook is fine. If you want a very portable, fast, fun device for basic surfing (eg GN, eBay, shopping) and playing games, then an iPad is great. If you use your computer for work, or even as a household management tool, then you probably need a laptop, as that will do everything the others do, and more.
