Are you asking how you install new programs with out a DVD or something? If this is the case, you can use a USB drive or purchase an external USB DVD drive to use to install programs. Also, you can download what you need to.
well you can use your g73 do do it insert the word disk and i believe you hold down shift or something and theres a few steps but you can save it to a flash drive dont ask me how big cause i dont know.
take the flash drive and plug it into your netbook and walla. or you can buy a usb disk drive for like 25 all the way to 100 bucks
now i beleive all the netbooks have 1gig of ddr2 not ddr3 like the highend laptops and all desktops so i dont know that will work with apps like that not sure of there requirements. you dont want it to take 5 min to open up a word document ya know.
