PDA... !! a properly equipped PDA can be a reasonable notebook alternative. Depending on the device, you can create and edit Microsoft Office documents; send and receive e-mail with attachments; and do a limited amount of Web browsing. You can even run PowerPoint presentations... so.. this for type of uses I will recommend PDA..!! although.. a 640x480 screen at a PDA is not small at all. it can provide a huge cantity of information (on the screen) in one moment.!!!!
