Hello Folks, Its me again. I am a long time Mac fan with very little Mac experience. I have had my iMac for two weeks and seem to be learning its capabilities and potential. I would like to set up a second monitor and now feel that the Thunderbolt display is the way to go. I hardly look at my Windows 8 laptop that I have had for only 2 months. Funny as it use to be the bees knees but the iMac has taken over that spot. Please discuss for me the pros and cons of the Thunderbolt Display along with any alternatives. I know this has been discussed before on these pages but please be patient with me. What to watch out for like dust under the glass. Please explain the installation process relative to the Mac. A Macbook Pro will come later in the year so I think this is a good move. If everything goes as planned the purchase will be made in 4 to 6 weeks. So please someone talk me out of this.
