Yeah, if he wants a 2 in 1, I definitely agree the Asus Transformer is going to be his best bet. Really cool how the keyboard detaches, too. Honestly though, you can find a bluetooth keyboard to pair with just about any tablet on Amazon for like $10, so I wouldn't necessarily let that be the only deciding factor; i pair a cheap, shitty keyboard to my Galaxy Note for school (the stylus support is sweet for notes), and it gets the job done perfectly fine
Yeah I agree, this is probably what I would do too. He's not going to get it until later this summer though so maybe he'll change his mind.
