You`ve got me all wrong mate. What I meant was that you wont have problems until Leopard is upgraded. ie bout 3 years from now. Your Yonah MB/MBP will be more than enough to handle most of the apps till then. Once that three-four year period is gone, your M
B wont have enough power to run latest apps to their best potential. And by
latest Apps I mean Heavy apps such as PS/FCP, not some iTunes/email/browsers etc. It`ll run all the apps but it`ll be atleast 50% slower than the newer computers(to say the least).
What made you believe I ever said that? You made that up yourself. Not me. Please try and read a post with your eyes open next time. I absolutely second your thoughts, except for the fact that I never ever hinted at this not being true. You are trying to correct me when I didnt say anything at all.
By a laptop/computer`s life I mean the time it can run the latest software/apps without any real difference when compared to the latest hardware on the market. So your brand new MB/MBP will be outdated and slow when compared to the hardware available four years from now. It`ll still run all the apps it was running at the time of launch. But dont expect it to run the latest apps as good as the newer Macs.
Also you can take other technological advancements into consideration. eg. the new MB has a builtin iSight and can run windows natively. These two features only were more than enough to make my 4 months old iBook G4 absolutely outdated. Also I always wanted my Lappy to be WideScreen. Plus I really like GLOSSY screen over Matte finish. Also you can count MagSafe, MagLatch,FrontRow. So even if I forget bout the speed difference between iBook and MB; these few features would still make my iBook outdated within a year of purchase. Thats why I calculate any computers life to be not more than 4 years. I know that the 1.33iBook would have served me for next 5 years atleast. May be more. But in comparison to the newer MB it seems
too slow and outdated. And it wasnt even a year old.
Now, I m new to Macs and dont know bout them as much as you might. So please help me here. Go back in time a lil bit. And tell me the specs of the iBook available exactly 4 years ago. Now compare it to the current 1.83 MB. Do you REALLY MEAN there`s not much of a difference between the two`s performance in various tasks/apps. Do both of them run FCP at the same speed. Or the iBOok is just marginally slower? Aint that margin bout 50% at least? OK. Forget FCP. Just load Tiger on both of them and note the diff while doing simple tasks like WebBrowsing, Movies etc. I m still sure you`ll find the difference big enough to distinguish between the two with naked eyes(OOPS. You dont try with naked eyes. Keep those specs on.)
If yes then I think I`ve proved my point. If no, then please redo the Math until you agree with me

. I can feel the diff between the new MB and my last iBook to be HUGE. From booting up the OSX, to apps launching in less than half time; I can never use that old iBook again. It is really really TOO SLOW.
Oh no No no. I just cant accept that award/compliment at all. AtLeast not till there are people like you on these forums who are 10 times more deserving than me
