I am looking for some advice. I am a teacher and I currently have some imac g3 computers that I let my students use for light web browsing and creating simple documents with neo office. A couple of students asked about purchasing some of my imacs so now I am thinking about upgrading and letting them buy my imacs (these are mine and not the property of the school system i work for). Ebay is where I am looking (which is actually where the imac g3's came from) and I am looking at either the imac g4 800 (http://cgi.ebay.com/Apple-iMac-M649...le_Desktops&hash=item588b0fc2e7#ht_1600wt_932) or an emac 1.0 ghz (http://cgi.ebay.com/Apple-eMac-Powe...le_Desktops&hash=item20b5599298#ht_3981wt_698). I looked at everymac.com and couldn't find any major differences between the two systems. The biggest pro for the imac is the smaller form factor but the emac is slightly faster and the glass screen is a little more appealing. I still have sticks of pc133 512 ram so I am planning on upgrading the ram. Any advice between the two machines would be great. (Please stick with these two machines as I know that the g5 is faster and intel is the future but I am working with the budget I have..not the school systems). Also feel free to tell me if the difference between the imacs I have now (g3 400) and the two machines I am considering is substantial.
