Anyone knows where I can get a keyboard to buy with the Ubuntu logo on the super key? If not where can I get some durable small plastic Ubuntu logos about 8 to 9 mm in diameter that I can use to glue on my keyboard?
I don't know of any with the Ubuntu logo, but I do know that Das Keyboards sell Linux Keycaps for their super keys (with Tux on it) on their keyboards. http://www.daskeyboard.com/products/. Canonical also sell an Ubuntu flexible keyboard in their store (with the Ubuntu logo along the side) but the super keys still contain the windows logo. http://shop.canonical.com/product_info.php?products_id=800. Hope this helps.
The Canonical store sells packs of stickers here that you can use to replace all the standard Windows branding on your machine, including two that you can choose from to cover the Windows logo on your super key--one orange-on-white, and one white-on-orange. Many of the other stickers come in these two variants, too.
Here is a place you can order custom keys for mechanical keyboards:
Pair that with the Ubuntu logo:
and this could be very cool!
If you are into mechanical keyboards, you can get Ubuntu Logo keys for Cherry MX switches from KeyboardCo.
I highly recommend the Turbot Water-resistant Anti-ghosting 87-Key Wired Mechanical Gaming Keyboard With Blue Switch. It's less than $40 USD (I paid $34) and it fits the keycaps from WASD Keyboards. A pair of Ubuntu OS Keycaps are only $6 on WASD Keyboards. There are other low priced mechanical keyboards as well, any of those will do so long as they are compatible with Cherry MX switches.
