I order this in the hope of get a nice portable keyboard for my android tablet . while the keyboard work fine on my desktop -lrb- run window xp -rrb- and my laptop -lrb- run Ubuntu 11.04 -rrb- , when I plug it into my android tablet , it be slow and unresponsive -lrb- the keyboard , not the tablet -rrb- . however , all my other usb keyboard work fine with the tablet . when I use the siig keyboard , it do not let I type as fast as I like to . run my finger across the top row of key will input only about two of the ten letter that should show up , and do show up with other keyboard . when I be typing normally , word will be miss letter right and left and nothing will be readable . -lrb- I type at around 70-80 word per minute -rrb- . this make the keyboard useless for write on my android tablet . that be say , the keyboard be a very nice convenient size , and work fine with my pc . so go ahead and buy it if you be not plan to use it on a android device . but go with a different one for android .
