I am considering either getting the Acer Iconia line of tablets or Microsoft Surface if it comes out early.
It really depends how you plan to use your device. All of the options listed above are plausible for media consumption (i.e. music, videos and ebooks). However, plan ahead the size, the weight and the features you want. I can easily recommend the ipad line, I did use it from the first version to the latest, although all stayed with me only for a couple of months before I sold it again to try a new one so on and so forth. Then I tried androids Line, and yes the Samsung brands have the lead in terms of android os on their system for tablets. I later learned that I needed a phone and a tablet rolled into one (I have big hands, Im a big person so I may need something in between). So I settled on the Galaxy Note and will continue with this lines upgrade until they cant created something along its line. Considering also I rely so much on Google for all my online stuff, Id rather concentrate on their mobile OS for connectivity with their system... This is imho.
