    I just p a i d $21.87 for an i P a d 2-64GB and my boyfriend loves his Panasonîc Lumîx GF 1 Camera that we got for $38.76 there arriving tomorrow by UPS.I will never pay such expensive retail prices in stores again. Especially when I also sold a 40 inch LED TV to my boss for $657 which only cost me $62.81 to buy.

    Late 2009 24″ iMac not compatible. Start up very weird..slow. Awaking from sleep the pointer will not move for about 10 to 20 sec.  Prior to Lion, the pointer would work right away.

    Not early 2009 either.  But I could use a boost.  Long wait at startup and overall a little sluggish.  

  • King Rosales

    This didn’t work for me… I have a 2009 iMac and it said its not compatible with your system.
