[QUOTE="cheesehole, post: 951183, member: 133287"] Historically, Li-on cells left in while the laptop is on AC have over time developed memory effect faster than laptop cells that were removed and set aside. The laptop makers know this, and because their sales team have recognised that when owners start noticing that a cell that used to take 5 hours to deplete, now only takes an hour to deplete, the owners either come back in and buy a new laptop, or buy a new cell. Ka-ching! Now we see why the laptop owners have such a disincentive to improve their product. Previously, apple did have the decency to suggest that MBP owners remove their power cell for up to a month at a time if it was used on AC all the time and it was also important to prolong cell life, but with the current design, that is clearly impractical. Now they may have actually gone against the grain of the rest of the industry and actually done something effective to protect their laptop cells, but I'm a cynic and I think they are still hoping for people to come back in, and buy replacement cells about a year after their original purchase. What we need are some statistics from MBA owners on the life of their built in cells if we really want to be confident in how the unibody macs will fare. If I was buying a unibody at the moment, I'd probably be looking to get the 3 year applecare as well, since then I'll already have paid for my replacement cells, and also anything else that wear out in the next three years. Apple's clever plan all along? [/QUOTE]
