Using the Jigsaw method in a classroom that has 5 computers would be rather tricky. Clearly computers are major benefit when used properly and when students are kept on task. Groups would have to be formed that would accommodate the 5 computers sparingly for each group. One thing that could be done is to have students use multiple resources at the same time and have the computer usage regulated between all the students equally. Or you can designate one student from each group to be the 'computer kid' for the day, or even designate two 'computer kids' for the day for each group that resort to the computers when something is needed.
There are many different factors involved in deciding what would need to be done, I would focus on keeping it fair and fun for each student.
Advantages to this Jigsaw technique would include, necessary cooperative teamwork, students governing themselves (making sure everyone is accountable for their own work and make it known that their work also contributes to the whole group). This could also be a good way for more advanced students to help students who are falling behind.
Some disadvantages might be that the more advanced students would not care about the failing students, it might cause discrimination of some students if not monitored closely. That also might cause some favoring if the teacher doesn't have the right mindset conducting this method.
Overall I see this method a fairly decent tool for the classroom and incorporating group projects. This is a major thing to prepare for in the real world, you can't succeed on your own in most situations. This tool is a great way to emphasize the importance of the individual in group work and prepare students for real life situations.
