    Pardon me for asking, but I'm unable to imagine how you are holding your hand(s) to bring any of your knuckles into contact with the sharp edge. I can't do that no matter how hard I try. When I sit at my computer, my knuckles are on the tops of my hands. Yours aren't?

    I've yet to see one person post a picture of these "scars". This claim would mean that you allowed your wrists to get to the point where they bled (Are you saying you continued typing while your wrists bled?) -- then healed to form scars... Ok whatever!

    And to the other recent poster, how on earth can one damage their knuckles whilst using their MacBook Pro. Please enlighten us.

    If anyone wants this thread to be taken seriously, please do not be melodramatic. State the facts. State how you have been using your computer. State any issues properly, because right now I am waiting for the post that complains about someone having their hands detached by their MacBook Pro!!!

    I hope that this helps make this a credible thread.

    Update: I bought a Speck case yesterday. The case does come right up flush to the palm rest area, nullifying the unibody's sharp edge. But, the Speck case has a sharp edge too! It's plastic so it's not as bad, and it could be easily sanded down to be more round. Mine was $50 at a local computer store. I'm not satisfied, but it could definitely work for some people, and protect your mac.

    In response to the above:

    I am a first time poster. I found this thread by googling my problem. How is this thread not credible? This is a support forum, and you are making a mockery of the concept.

    Personally, I use it sitting at a dining room table or on the couch with the MBP on my lap. The underside of the knuckle (or joint) where my right pinky finger meets the palm of my hand rests on the edge of the MBP near the trackpad.

    If I use an old Toshiba or HP laptop laying around the house in the same fashion, I have no ergonomic complaints. In fact, since I have used laptops for years and never had such an immediate ergonomic complaint, I was totally unprepared to even look for such an obstacle when shopping for a new laptop.

    I can take some pretty pictures of my hand tomorrow and post them here, but that doesn't solve my problem, and I'm certainly not interested in proving myself to anyone.

    If you want to play that game, I'm referring to the palmar metacarpophalangeal joint. You are free to google it. Sorry, but I won't be responding further to your posts in this thread, as your responses are bordering on trolling.

    Coincidentally, a friend of mine recently offered me some chemistry trivia that aluminum oxidizes almost instantly but unlike steel (for example,) oxidized aluminum doesn't flake off allowing the metal underneath to oxidize. Soooo... Assuming that's the case, oxidization/corrosion shouldn't be an issue. As long as you are happy with the finish you get, go for it. I read on another site that someone lightly sanded the edge and then polished it just a bit with an emery board. I'm pretty tempted to do the same.

    I'm surprised such a finely machined case has sharp squared edges instead of finely rounded ones.

    I think there are more than a few who think the edge's are too sharp. They are way too sharp in my opinion. And my posture works for me so mind your own. You meant to just say "they look great", me thinks.

    Why can't I just round them over with the sander? Is that really any worse than the normal wear and tear this case will get over the course of it's 3 yr warranty.

    I do not understand why moderators allow this thread to continue.

    This is a support forum where fellow users help other users with software or hardware problems.

    We cannot change the design of the MacBook Pro. There is no solution to this problem. The only thing that can change the design of the MacBook Pro is the number of sales. Right now, those sales suggest that this design will remain for a very long time -- and for that I am very grateful!

    Curious, what did the edge look like after you filed? Was it the same color as the rest, or is there a surface coating (anodized finish?) that got removed?

    I agree it shouldn't be this way. But some self-inflated-ego designer-type thought it looked so cool to have the lid and bottom close with nary a gap. Form over function.

    Hey, I've been using Macs exclusively since 1987, and I have a problem with it. Nothing wrong with you! Ignore those who aren't being helpful.

    Did you read the post from the guy who filed the edge? Hoping to find out what it looked like when done.

    The discussion continues because people are looking for a reasonable solution to a real problem, without taking a file or Dremel ® tool to their expensive laptop. A good looking, inexpensive solution will be available soon, I'm sure.

    Using a Dremel or a file is overkill. Get a regular old emery board (nail file) and run it lengthwise lightly along the edge a couple of times using the fine side. Problem solved. The aluminum the case is made of is a fairly soft metal and it takes very little to knock the edge off.

    I personally don't have an issue with the edge. I did smooth out the corners at the lid notch, they were very sharp.

    since the surfaces you are dealing with are all brushed and modification with a file or a sandpaper will create much more fine (shiny) surfaces ...

    I'd strongly discourage such behaviour since it is irreversible

    Hi Frank,

    Have u finally managed to get rid of the pain in your hands?
    I am suffering from same kind of pain. Doc has suggested not to use computer for a while. Its not that I am new to Mac but now whenever I am using my macbook, while using the trackpad its triggering pain on certain parts of my hand/wrist and arms.

    Kindly suggest if you have used some other posture to use the trackpad?

    Thanks and Regards,

    Had to dust off the old apple id just to bup this thread! I know a great deal more about metal working than I do about computer tech, and I got to this thread by by typing "MacBook Pro sandpaper"

    Now I got to thinking "MacBook Pro sandpaper" because I've had a brand new little MBP 13 sitting off to the side of my desk for almost two months now, and just can't seem to feel comfortable with it! It just seems so angular, and the edges seem to grab at my hands, especially when I'm using the track pad and key strokes for editing documents and drawings. I also like to work in bed early in the morning, and watching movies late at night, and the chemistry just has not been there. She's beautiful and well-built . . . but so cold!

    After all this time, my business partner has had enough and announced a couple of days ago that he would take the book, freeing me from the sense of guilt and opening the door to my return to white acrylic. Of course now, sitting at the desk migrating my stuff off the MBP, I'm having doubts about giving up firewire for non-conductive plastic, and part of me is wondering whether a light sanding might not do the trick . . . .?

    I've got tons of experience working metal, and if the edges were the only issue a tiny piece of 400 grid sandpaper (automotive) wrapped around a little block should that corner off with 5-7 strokes on a side, leaving an eased edge. And I dont think this would violate any warrantee. I've kept macs on construction sites since I first saw OSX; they breath dust all day, get thrown in shoulder bags with a tape measures and other hard/sharp objects, to be hauled home and back. I have never had an Apple employee suggest that they would not honor Apple Care because of superficial case damage. (Now *liquid damage* and *cracked screens* are a totally different issue!). No way gently eased edges are going to be noticed, much less used to void a reasonable claim.

    Wondering if eased edges would make enough difference for me, I then started wondering if anyone else had tried it yet. I'm actually just glad to hear that other people have an issue with how this otherwise perfect tool feels in the hand. My friends, biz parnter, and employees all think I'm crazy (and offer to take the MBP off my hands!). That makes me neither a hater nor a troll; just a guy who can't believe he is going to have to by a MB with no firewire port!
