Paul and I.T. are synonyms. If you need help with I.T.-related stuff, call on Paul. His experience with Android phones goes way back to the ancient single-core-phone days. But, he keeps himself up to date, so now he has a dual-core beast in his pocket, and is looking forward to getting his first quad-core monster, and when it comes, his first eight-core phone. Perhaps he should be called Mr. X-Core, where "X" equals the number of CPU cores.
