i agree...if u have the leyboard, mouse, and monitor, then jsut buy a tower...you can get one for about 500 bucks or so and it will be a nice one
or...buy the parts and put them togather into a nice top of line comp...DISCLAIMER: do not do this if you hate technology, if it hates you(read: every time u touch it something breaks), or if you have 2 learn how 2 do it cause it will be a waste of time that way
then if u neeed a pda get one but not 2 expensive and upgrade again in a few years
or get a laptop but if you are not doing anything graphics intensive, programming and compiling intensive or very graphics intensive gaming...as in you just use it for bascics like word and so on....there in no need to spend 1500 on a laptop...you will be throwing $$ away
i would recomend getting a pda that can do word and so on and get a new desktop...that way you have the best fo both worlds
hope this helps
