Joshua,
As I responded in the previous thread, I tried out a Samsung ATIV 500T with an Atom chip, 2GB RAM and a 64GB SSD, but I paid $599 plus tax. It can be had on Amazon now for $549. It ran full Windows 8 but was unfortunately very slow to load and to scroll resources using touch in Logos. It has the same specs as other Atom-based Windows 8 tablets, except that it has an active digitizer. An active digitizer is a must with Logos because Logos is not optimized for touch and you need to be able to use a stylus to navigate.
I took the 500T back and bought the 700T, which is much, much better for running Logos. However, it is outside of your price range. If you can deal with the performance hit, the 500T is otherwise a great tablet for the price.
While there are other Atom-based full Windows 8 tablets out there for under $500 (Asus, for example), I don't know if any have an active digitizer. All of these tablets have the same specs as the 500T without the active digitizer, so performance will be approximately the same.
Thanks brother Anderson. I do so hope these Tablets work better with Logos 5 soon.
I would like to be free of my Toshiba Laptop someday.
I liked ThinkPad Tablet 2 but heard the wifi cuts out at times.
I found this online today.
