The latch button on my MBP is inset on my machine and sometimes its difficult to open. That is, rather than sticking out its flush with the case. I have to use the tip of my finger to open it up. Sometimes it doesn't unlatch right away and when it does open the lid -- it does not spring up like it did on the Powerbook. Is that just the way they're designed?

mine is the same way - much more annoying to open than my previous 12" powerbook. Are others noticing this as well?

Mine definitly "springs" up a half inch or so - I'd say there's something amiss. Are you near an Apple Store? Otherwise you could call. I realize it's not a huge issue, but I'm fairly certain it's not supposed be that way.

My button is flush though, and I too have to use my fingertip, pretty sure that much is normal.

I just chalked it up to having big hands. On my old iBook I could just press my thumb flat against the front where the latch is and it would pop open. On the MBP I have to almost use the tip of my fingernail to get it to pop open. Kind of annoying but I hardly close mine anyway.

I agree that the lack of springing is not right. With regards to the complaints about the button being flush with the machine, however, that could be a response to earlier complaints from PB owners that their 'books would wake up when the button was pushed accidentally while being carried in a bag. It may be more difficult to open this way, but it's also less likely to open unintentionally, which seems like a good thing to me.

Same here. I have to almost use the tip of my fingernail to pop my MBP open too.

And I thought it was because I have huge hands. Good to know that other feel this too.

Glad to know that there might be an actual design reason for why it's harder to open (than a PowerBook), though!

The amount of "springing up" also has to do with the amount of force pushing against the lever. I've had a PB with a slightly bent lid, so that the lid would come very close to the base. That meant when you pressed the release button, it hardly sprung open - lack of force (by the spring). If you then insert something between lid and base to enhance the gap (like 2mm of rubber) and thus increase the spring's force, the lid will spring up more when released.

Basically it all boils down to Apple not making sure the gap is at minimum >1mm. The rubber pads they use are too far away from the latch and they're much too small - maybe because some people complain about the gap. OTOH keyboard marks on the screen came from exactly this gap being to small.

This is also the reason most 12" PB users don't have the problem. Like the iBook the 12" PB has larger rubber pads and they're at a smaller distance from the latch. If you take a look at both kinds of pads, you can;t miss the difference.

I don't know about you, but my MBP has rubber pads right next to the latches, in addition to the ones on the outer edge of the screen.

You're right, my bad. The pads are so damn small I didn't even notice them there.

On the 15" PB, there were no pads next to the latch, just the ones on the side.
