I've had my new MBP for several weeks now, and never really used the trackpad much as I tend to have it hooked up to an external monitor and use a stylus. However, now I'm using it more in 'mobile mode' I'm noticing something really quite annoying and frustrating about the trackpad. When you first use the trackpad, it feels fine, if a little 'lighter' than my previous Powerbook. However, after using it for a couple of minutes, I start to notice something strange. The trackpad is slipping slightly, under certain types of movements. It is usually the small corrective movements that you make when you shoot straight to a button, then move the cursor slightly up or down to get it on target. Usually this is done unconsiously without thinking. But with this trackpad I keep getting it wrong. It is like the cursor is slipping slightly, then jumping slightly. It is quite strange because it is sort of intermittent. But overtime it is a very, very different experience from using a Powerbook trackpad. I've tried turning off 'ignore accidental input' and it doesn't help. I've tried adjusting the tracking speed and that doesn't help either. To do a little test, I've tried moving my finger very very very slowly down the pad. And after a bit of practice I can actually get it so I am moving my finger down, with pressure, on the pad, and the cursor stays stays stationary, without moving. So to me this points to a problem. It shows that the trackpad is somehow slipping slightly. Has anyone else noticed this? Is there any point in me going to the Genius bar and trying to explain all this? I'm worried they'll just use it for 20 seconds and say, 'yeah it works' and I won't get anywhere. This is the main drawback with my MBP. Another minor point is that the fan gets very noisy under load (ie when I have Photoshop and Illustrator running under Rosetta). But most of the time it is very quiet. It was a strange feeling when the fan first came on, I was working away and there was this slowly increasing noise, and I was thinking, what's that? Sounds like a spaceship or something... On the plus side the MBP is a hell of a lot faster than the Powerbook. Photoshop is noticeably quicker even under emulation. It just doesn't feel quite as polished as my old 1.5GHz Powerbook. I loved that machine, everything seemed to be perfect about it (except the speed of course). Anyway, the main problem is the trackpad... any thoughts?
