I recently did the search for Patrick's comments about battery pulls, and then had a conversation with CB friends about them. While I may not be convinced that one should never pull one's battery, I have been experimenting with memory management without bat pulls since my upgrade to .69.
I have relaxed a little, and only check free memory once a day - in the morning when I get up. I have noticed that my free memory after clearing my browser cache, running the memory cleaner utility, and doing a reset is right at 27.3 mb. Over a 24 hour period, I've found my free mem will drop between 2 and 5 mb - usually closer to 2 mb with .69. I do the above steps each morning and forget about memory.
I have found that my method works very well for me. So far I have not had any issues with free memory because my berry is very consistent with how much it drops each day. It is nice not to worry so much about it. I am not going to say to never pull your battery because there are times that you have to pull it - like when your device locks up or is running slow. I don't think a battery pull hurts anything at all and it will help someone who doesn't do routine maintenance like I do. However mine hasn't locked up since my upgrade.
That's my 0.02 cents.
