Hi all, I have mroogled this but didnt come up with anything..... I managed to get my hands on my new baby last Friday...... new MBP 17" i7 with anti-glare! My wife also has a 2009 uMBP 13", which I have been using since Xmas while waiting for Arrandale! I use a stand with a apple wireless keyboard and wireless magic mouse. I have been having problems with the new 17" machine - the mouse and kb work fine for about 30 mins then the mouse gets really slow and jerky.... and the keyboard gets slow as well and starts displaying double / triple keys when typing etc. The only way to resolve the problem is to reboot. If I unpair the mouse and keyboard and repair this doesnt fix it - only a reboot works. I phoned applecare and they instructed to create a new test user, which I did - same problems. Reinstalled OSX (machine was only 2 days old though!), and this didnt fix it. So, I took the machine back to my Apple Retail store and swapped it for a new machine. Finally finished setting it up again yesterday, and the problem started AGAIN - ARRRRGGGGGHHHHHH! So it would seem that unless I have had two faulty machines (highly unlikely) it must be software related? I have been trying to work out what might be causing it - but running the machine without Parallels, Little Snitch, 1 Passowrd....... things which I thought could have been related to the problem..... no luck. I basically ran the same system on my wifes 13" before I got the new machine and I had no problems with the mouse and keyboard...... BTW : I have also changed the batteries on both the mouse and keyboard. Anyone else having this annoying problem?
