MBP going crazy mouse and keyboard and everything in between

Question

Oh this is my third attempt at posting this thing and I am ready to slam my MBP in a brick wall!!!!! the only reason i know this time it won't mess up is that i am typing from my Pmac G4.
anyway.... two issues... the first one happens occasionally while i am typing, the last 2 times while i was typing in this post to ask for help, for no reason that i can see out of nowhere the computer just started deleting everything i had typed as if someone were holding down the delete key, i did the updates recently and fixed the issue the update had with version CUE, but now this is happening
the other issue unlike the first locks the keyboard and renders it useless, or sometime it will lock the mouse/trackpad, sometimes if i put it to sleep and wake it the problem is usually gone temporarily, but that doesn't always work.
last thing i should mention is that this is my 3rd MBP the first won was giving me the green lines on the screen, the second was whinny and hot, and now this.....am i just unlucky or do they just sell their craptacular laptops to me only

Answer 1

I just got home from the apple store and discovered a whole new problem with the laptop, when i woke it from sleep my desktop icons were all distorted as well as the menu bar on the top. Luckily, given that this was my third MBP the management at the local apple store agreed to allow to me to exchange the machine beyond the 15 days which have already expired.
The best part is that the 1.83, is discontinued so i should be getting a 2.0 plus a one-hundred dollar refund as the price has also dipped since i purchased it, i would have still prefered to get a working machine back in march when i made the initial purchase, but looks like i'll be spending most of tomorrow, re-installing all my applications.
Hopefully for the last time!
