"Good for both entertainment and work uses."4.0 starson by jeff_comment
Pros: 1. Microsd/usb, open system vs closed for ipad.
2. Keyboard feels great, which makes this good casual business use, vs almost only entertainment value of ipad.
3. Can use normal windows office docs
4. Even with keyboard it is very light to carry
Cons: 1. Only hold 25 emails at a time in an email account. Very difficult to browse email history. This is a big drawback. So I still use blackberry for emails.
2. There is slight lag when I use finger to move page up/down. Not as spontaneous as ipad.
