I have been lurking the forums for a while now, trying to gather all the info in order to get the best tablet. First I'd like to say this forum is loaded with very knowledgeable members and I thank you all. I believe I have narrowed my selection between the a81e and the x5a but have a question and wanted to seek further information. From what I gather the a81e does not Have an HDMI out, I teach classes and feel a way to hook up to a TV or projector can really help me get the most from my tablet experience. The x5a does have HDMI out but really haven't found any reviews. I would hate to risk performance and smooth operation for the HDMI out. Any info and input is greatly appreciated. 2.1 and 2.2 is fine as operating systems. I like option to change batteries on the wits. I guess ill have to learn to live with whatever option I choose. Thank you in advance.
