The technical equipment was instrumental in my decision to buy. The choice was for me the Samsung 10.1, the Acer Iconia, Asus Transformer and the iPad2. The Samsung is not expandable enough (no SD or USB slot) and too expensive for me. The iPad2 has given me too many technical constraints (no Flash, etc.). The Acer would have been my choice. Ruffed has Asus by price and Tastaturdock that is quite lush but priced at 149, on the other hand extends the battery life. The non-optimal housing processing, I can confirm only partially. This is certainly better, but does not justify a 1-2-scoring. Conclusion for me after a long decision-making process: there is no panacea in the trays in djesem price range. The best device for pure tablet operating without a keyboard in my opinion is the Acer. Who needs a keyboard, is better off with the Asus. All subjective and subject to change. Ultimately only solution: look at, touch, try and think carefully about what techn. Equipment is important.
