I just checked, and since a year ago Apple uses pull tabs instead of glue - so the batteries are relatively easily replaceable.

As a side note though - how often do you replace batteries in notebooks? I think the only one time I ever did it was in 2008. I think most of my Macbooks survived over seven years each, and were passed on to my family - the batteries were never an issue - neither for me not for others who got my laptops.
