Rhetorical Functions in Academic Writing: Comparison and contrast

Exercise 2

Students at university need to organise their lives, control their finances, keep records of phone numbers, remember assignment and exam dates etc. Some students use paper diaries and notes for this, but the use of electronic Personal Data Assistants is becoming more popular.

The table below compares 19 PDAs.

Using the information given in the table, recommend one of the PDAs for general student use. You will need to describe what a student has to do, describe some of the PDAs, compare and contrast the ones you have chosen, look at advantages and disadvantages and finally recommend one.
