回答: <原文> steve jobs changed the world. he created computers for everyone to use. computers were thought to be used only in offices by professionals.but, steve jobs created smaller computers so that they could be carried from place to place, for a cheaper price, and by everyone who wants one. <修正案> steve jobs has changed the world. he has created computers for everyone to use. computers were thought to be used only in offices by professionals. but steve jobs has created smaller computers so that they could be carried from place to place, purchased for more affordable prices, and owned by everyone who wants one. - ...professionals. の後にスペース(←細かい!) - but, のカンマを削除(butは接続詞なのでその後に文をつなぐのにカンマは不要かと思います。) - purchased for more affordable prices, and owned by everyone...(so that のあとでthey could の例を3つ並列していますから、carried, purchased, and ownedと動詞を並列すると並列がわかりやすくなります。また、priceは一つではなく複数の価格が考えられますので、more affordable pricesと複数形にしました。) - has changed / has created (スティーブ・ジョブス氏がやったことは過去の出来事ですが、その出来事が過去のその時点のことだけでなく、今にも引き続き影響していると言うニュアンスを出すとすれば、過去形ではなく現在完了形がふさわしいと思います。つまり、彼が世界を変え、いまだに私たちはその変化した世界に生きている、と言うニュアンスです。) いかがでしょうか。
