Because it does so well with its two flagship products -- the iPhone and the iPad -- Apple now accounts for 19.9 percent of all US consumer tech sales based on revenue. The result far outpaces any other company, even arch-rival Samsung -- which saw a similar gain in percentage but remained below 10 percent in share. The gains for the two tech giants came at the expense of other companies, including HP, Dell and Sony, which saw a combined drop of $9.5 billion in revenue.
