no problem. too bad it wasn't enough to make a difference.
yeah, it's definitely not optimal. I am hoping they improve pdf on upgrades, but as you say, it's not their main goal, which of course is making money
.
i was definitely disappointed as well, i was counting on being able to do proper annotations (and highlighting) on pdf, but since it's only about 50% of what i wanted the glo for, i decided to make do with those functionalities, which at least were much better than it seemed when i first got my glo.
the kindle PW does seem to have better zooming abilities on pdf, but i haven't seen any evidence that annotations and highlighting is well implemented (or evidence to the contrary either)
good luck finding a reader that suits your needs!
