Arguably just as impressive is Apple's revenue during its quarterly reports, with it repeatedly setting new records for revenue.And, we're not even including debt for Apple or nations in question — which would move Apple even further up the list.Continuing the country-level theme, Apple's Q3 gross margin of $35.9B would put it in 99th place ahead of Sudan ($35.151B) and behind Estionia (98th, $36.3B).Over the last four quarters, Apple spent $25.2 billion on R&D, which is more than the GDP of Bosnia and Herzegovina (111nd, $22.4B) and not far off 110th place Iceland ($25.5B).Both iPad and Mac managed similar Q3 revenues of $7.22B and $7.38B, which is just behind Somalia (151st, $7.39B)."
