Have now tried connecting to external monitor and inserting/reading a SD memory card with success. The F4 key is used to toggle from screen to monitor and back. Under the 'gear' at the upper right corner of the main screen are where the 'display settings' are found. The only setting for available screen resolution. Since the default screen setting is pretty good using the external monitor most likely would be utilized for presentations not viewing for use of the LapDock 500 Pro. Once the SD memory card is inserted you will get a notification by the phone window and by using the 'File Manager' you can see it as a full SD Memory card vs the internal Micro SD card on the phone vs the internal memory of the phone. You must unmount the SD memory card prior to removing it and that feature is in the 'File Manager'. Found that both windows (phone and webtop) can be enlarged over the top of each other. At the bottom right hand phone view screen is the toggle key for the phone view. Once the phone view screen has been enlarged either portrait or landscape clicking on this toggle key will bring the phone view back to its original position and size, a nice feature. You can also have more than a single webtop window open with multiple tabs in each window. Any of the webtop applications can be open at the same time. Example I currently have a single webtop window open with firefox on it, the music application open and playing, the file manager open all the while having my phone view window open. Pretty impressive if I say so. I personally use 'DocumentsToGo' application for excel/word/pdf files on all of my devices which are a Razr Maxx android phone, Dell desktop, Toshiba R705 notebook, a Apple Ipad 2, a original Transformer with keyboard dock station, and now my LapDock 500 Pro. I also use 'DropBox' for web storage of all of my work files. By using these two applications on all of my devices I can access any of my work files from any device no matter which OS the device uses. The LapDock 500 Pro handles this either through the web DropBox site or through the phone view window. When opening up a file I can expand the phone view window to landscape and view or work on my files at any time. Another very cool feature. At this point the only down side I have found to the LapDock 500 Pro centers around the 'slowness of 3G' connection. I anticipate this will not be the case when 4G gets to my location or when ever I am traveling into a 4G area of coverage. The other down side is the track pad. I have found that for general use the track pad is fine. For more complicated functions the USB mouse I connected worked great. Complicated functions would be resizing window views as well as using other webtop applications. All in all I am very pleased with the LapDock 500 Pros function and features. I would utilize the device when traveling since it will assure me of web access on a workable screen size vs just using my phone. At home I would utilize my two tablets more than the LapDock 500 Pro. When doing multiple spreadsheets with multiple tabs that relate to each other my desktop or laptop will be the devices of choice. Lastly if your forced to use 3G with the LapDock 500 Pro be patient would be my advice since it is not a fun experience. Tethering my phone to either of my tablets creates a faster response while using the tablet than the experience with my phone connected to the LapDock 500 Pro but thats just the way it is. Once 4G is in my area that may change. One closing comment would be about the position of your phone when connected to the LapDock 500 Pro. I have a Raze Maxx as I have said before and it sits inside of the tray about 3/4" when mounted. It also sits in a horizontal position with the connection strap on top. I have moved the LapDock 500 Pro around a bit from table to desk to counter top with the phone in this position with no issues. Sitting my phone in the landscape position with the docking cable on the right side was a concern to me and in fact the phone slide out of that position dangling from the dock by the cable a position I do not recommend. If you have any questions I have not covered in this review just ask away and I will try to give you my experience or test what you would like to know.
