Pardon me if this gets double posted.Mods feel free to deleate the first one. I just ordered a HP pavilion ze4904 that should be here in a few days.Got a heck of a deal on it.For 3 days only Office Depot is running a sale on what they call thier KIosk program.Go in order it and they give you a $330.46 rebate by mail. Computer wound up costing me $615 bucks. Here is what I got. Intel celeron m350 Windows XP of course Intel extreme graphics 54g 802.11 wireless connection 15.tft xga 512 sdram 40 gb hd dvd/cd-rw combo drive 6 cell ion battery Anyways back to my question.I want to get a extra battery for it.Is there a place on line that sells them cheaper than dirt? AND ARe the ION batteries the kind that you don't have to worry about the memory in them??I always get confused on that point.Some batteries you have to discharge all the way before you can charge them and others you don't. This computer is by far not the fastest or best on the planet but it beats my old CTX 700 by a long shot.
