Technologically challenged

okay i think i am a little bit behind the times as far as computer technology, my newest macintosh i have or will have once the post office decides to drop it off, is an iMac tangerine 266mhz, i am writing this entry on a performa 6110cd with a 233mhz g3 upgrade and 64mb of ram, my newest pc is a pentium 3 500mhz. My newest laptop is a soon to arive 5300cs. This equipment does what i need it to do, i see no reason to upgrade unless something breaks beyond my ability to fix it.
