I'm considering this tablet. Can anyone answer the following: 1. Multitasking - can you surf the internet and play music at the same time? 3. Can you play video from a USB flash drive? How about from a portable hard drive? 4. Can you connect a keyboard? 5. Video performance: How good is 480p using H.264 format? Will it play smoothy at 1500 Kbps? How about 720p @ 1500 kbps? Does video look "crisp"? What about contrast in dark scenes (this leads to my next question on brightness)? 6. Is screen brightness OK or not bright enough? 7. Adobe Flash: In fullscreen can 480P play smoothly? How about 720p? Thanks in advance!
