My expierience with Lion GM (11A511) Macbook Pro 17" 2011 I did a clean install on a new OWC 240Gb SSD. - Intel HD3000 graphics mode is still jerky. For me this a hugh let down. This means every MBP owner will have slow graphics by default. (read: general slow GUI animations etc..). Switching to Radeon HD6750M results in very smooth GUI operation. Within SL the Intel HD3000 performs smooth. This can only conclude Lion is more GPU hungry compared to SL. A pity. - Keyboard backlit still cannot be disabled in the preferences. However, you can turn if off manually with the keyboard F5 and F6 buttons. - Mail is crashing more then with DP4+Update. More precise, when deleting threads can result in a random crash. - Booting is very fast with a SSD. Less then 10 seconds counting from pushing the on/off button. Shutting down is prompt (1 second) - TRIM is disabled for the OWC SSD (as expected). So no TRIM support for non-Apple-SSDs - The video example for Launchpad and Show Desktop are funny. Four finger wipe squeeze .. it does work with some practice. - I cannot disable the 'Reopen windows when logging back in' in the preferences . No, 'Restore windows when quitting and re-opening apps' disabling does not work. - Spotlight is much faster compared to DP4. First initializing took less then 5 minutes. Previous DPs took sometimes 30minutes and more. Not sure if this is representable. - Safari crashed a couple of times when using the wipe features. Thats it for now..
