OK, everybody. Here it is. The Sony Ericsson Xperia X10 mini pro, the tiniest darn Android phone you've ever seen, let alone one with a horizontal keyboard. For being as small as it is, the keyboard was surprising usable. More so than the Motorola Droid's (though that's certainly not saying much), but not nearly as good as the HTC Touch Pro 2. It is what it is.
