I have an external Bluetooth Keyboard that I use with my 2 year-old Blackberry and there are all sorts of problems (e.g. lag when typing, functionality in some applications but not others, etc.) I am about to buy a tablet, and I want to know if I will have any of the same problems, assuming I purchase a highly rate, Bluetooth 4.0 keyboard. Are the problems I am experiencing endemic of the world of Bluetooth keyboards, or is it just the fact that I am using an older cellphone with an older Bluetooth rating? I do not really care if the keyboard connects with the tablet, unless having a keyboard that is native to the device, designed specifically for the model of tablet, will improve functionality. Will a good Bluetooth keyboard basically serve me as well as the keyboard I am use to on my laptop, or will there be any disadvantages?
