Keyboard ?

[Robert11]

Hi,

Going crazy with the typing.

Spending more time correcting typos that appear on the screen that are different text from what
I thought I had apparently typed in.

Is there a decent very small real keyboard I can get for under $50 or so that would fit comfortably on my lap ?
And, lightweight too.

What do most of you folks do, and use ?

BTW: any good typing suggestions ? I use one finger on each hand to type, and am a reasonably fast typist, but not extremely fast.

Thanks,
Bob
