MikeBZH, I hope you had a nice vacation in August... I have been currently using a pair of 24LC1025's to log data from my Solar Tracker which uses an 18F2620 running @ 40 Mhz. I have had no problem with them even in the below zero temperatures we have up here in Michigan...
I do not compile with PBPL as I have used the internal flash to about 3/4"s of its capacity. It's nice to see you back...
