What is the opinion of Reddit about the
Spider E-Series Ultra Slim Rechargeable Bluetooth Keyboard (E-BTKB-B001)?

Something like this for the keybd? http://www.amazon.com/Spider-E-Series-Rechargeable-Bluetooth-E-BTKB-B001/dp/B004JO5XH8/ref=cm_cr_pr_product_top?ie=UTF8

OTOH, if price isn’t much of an issue, you could go get a regular BT keyboard/mouse and invest in some Energizer Lithium AA/AAAs. They’re super pricey, but for low drain electronics they last a long time.
