Because they are reasonably affordable, netbooks are a cheap alternative to full laptop computers.
Here are some of the pros:
The small size of a netbook makes them easy to fit in a backpack.
Netbooks are affordable, especially for parents who face a financial load in buying school supplies.
Here are some of the limitations of netbooks:
They are designed primarily for Internet and email use.
Word processing is possible with a netbook but Microsoft Office products are generally not installed. Ask before buying (or consider an external CD player that you can use to load the program from a compact disk).
You cannot play games, or play CDs or DVDs directly from the unit. Check to see if your unit will support an external CD/DVD player.
Always price shop so you can get the best deal. You can take a look at some netbooks for under $300 here.
