How "Tool Man" could change the way he works.

PDA= He could Carry this around with him and enter customers home addresses, email addresses and phone numbers; this way he will have all his customers details on him all the time.
There is also a calender on the PDA so he can enter appointments and then the PDA will tell him where he has to be and at what time, it would be like his personal organiser.
He could have a price list of all his products etc and have a list of what people owe him.

GPS= This is like a Satellite navigation system, this would be very useful for him and would not only be easier but would save him a lot of time as he wouldn't have to look for a location on a map, instead the Sat Nav would tell him where to go and he would be more likely to arrive on time to places. The GPS would be linked with the PDA therefore would have all customers address' on it.

Laptop= This would be very much like the PDA, though the only main difference is the size of the screen. He could use a laptop to store information; on customers, price lists, amount owed, invoices etc. The laptop would be very useful as it would save him having to visit the office as much and he could just do his work where ever he wanted in spare time.

Mobile Phone= would be very useful as he can communicate with customers, although if he had their email address it would be cheaper for him to mail them. Though a mobile phone is very important to have imidiate contact with the customer, for example if he was stuck in traffic he could let them know he would be running late.

Disadvantages of using this technology:
He would at some point need to visit the office to print off invoices etc.
Over Reliance; if it were to break he could loose all of his information therefore he needs to have a back-up system, i.e carry a road map with him just encase his GPS broke.
