Apple didn't actually invent the modern laptop; that's just Apple PR. The Xerox NoteTaker, Osbourne 1, Dulmont Magnum, Toshiba T1100 and Compaq SLT all get credit for the “first” in different ways – and all in the 80s, before Apple produced a single computer that could be called a “modern laptop”. (Except the NoteTaker, which was 70s.) I vote the Toshiba T1100 as the first modern laptop, btw.
Apple was the first to put a trackball in a laptop (though that laptop was, in the rest of its design, at least five years out of date – hardly modern), invented the laptop palm rest, and – much later – was the first to put an Ethernet port in.
