Netbook

• Some Advantages of a Netbook
• Relatively low cost
• Small Size making it easy to use on the desk or
  in the field.
• Screen quality - LED vs. LCD Technology
  brighter display than cell phone or PDA
• Very light - weighs about 3 pounds or less.
• Portability from its small size and weight
• Longer battery life, up to 6 hours at full
  brightness of display
• Uses standard computer software unlike cell
  phones and PDAs

• Some Disadvantages
• Limited operating system choices
• Limited access to peripheral devices like CD-Rom
• Often restricted telecommunications access
  usually no phone modem
