2. Now, people can check the stock market or call home while waiting in line at the market.

4. Who knows, in the future, land line telephones may disappear altogether.

Explanation:

This is the most logical order for these sentences. Sentence 3 should be the opening sentence because it is the one that introduces the main topic of the paragraph. Sentence 1 follows, because it introduces the background information. Sentence 2 develops from this background and introduces the description of how things are now. Finally, sentence 4 provides a prediction and concludes the paragraph.
