Finally, am back to good and old school technology. Means, I got my new HP PC laptop nc6400 back. After fighting with Macbook Pro for last few months and the problems were never ending and most of the time the Macbook was kind of useless to my prime time production. It gets too hot within an hour of time and on and off everyday the OS hangs and needs a reboot and all my unsaved documents were lost. So, finally I have to make a change.
After I got my HP laptop from Yahoo!, reinstalled Vista on top of XP Professional and got the setup as needed. Now the things are in normal control and I can see that my productivity was increased and am am spending more time in getting the real work done rather than fighting with endless problems. Even though I still have another Macbook Pro, not sure I will spend that much time as I used to spend earlier.
