Hey guys, I finally got 2.7/16/512 rmbp last weekend. I did notice some scrolling lag on theverge.com compared to cMPB in store. I was told that the problem is with browsers not using multithread and what not.. At home, I noticed lag in mission control that went away after switching to Nvidia graphics with gfxcardstatus. I then installed the three updates including 10.8.3. The gfxcardstatus doesn't work anymore. After opening the lid, the macbook stays blank for 45 seconds and isn't responsive at all. After 45 seconds, I can login. I was very excited to have a powerful all in one machine after spending $2500 and wanted to keep for long time :/ Should I return it and wait for next gen ?
