Okey dokey -- I have what amounts to a almost new 400mhz Tibook. Why almost new? Because I have a 7 month old brand new logic board. 7 month old new keyboard. 7 month old new top case. 2 week old new middle case. 7 month old bottom case. 6 month old Hitcachi travelstar 40 gig hd, 5400rpm, a 1 month old new Airport card, 2 six month old Kingston 512K ram chips -- plus i keep the top case and middle case in their original plastic protector wrap, plus i have an iskin keyboard protector -- so the case is untouched -- so the only thing "old" about my old Tibook is the battery, the LCD and the DVD CD rom drive which are all great. My question to you today is -- I love the tibook -- should I bother buying a later model or upgrading the CPU when ALL I do is surf the web, use Word and email? I don't game. I rarely even watch movies and I don't have an iPod yet. (It came with a Smartdisk Titanium cd burner external because it doesn't burn) Should I buy a Daystar 550mhz CPU upgrade? Should I go to a 7200 rpm HD? Because I have a feeling that since my useage is so basic, that even if I were to go to a 1ghz Tibook, IT STILL WOULD BE around the same speed for the way that I use the machine! Am I right to just hang on to my pretty new old Tibook as is -- or is there any real time speed bump that I would enjoy with either a CPU/HD upgrade or a maxed out 1ghz Tibook? Thanks guys -- I really thought about it and don't know the answer.
