The keyboard you're typing on is probably gross as hell, and it isn't doing any favors for your posture, either. Consider replacing it with Microsoft's stalwart ergonomic split keyboard, which is on sale for $30 from Amazon at the moment.
Microsoft's been making ergonomic keyboards in one version or another since the 90s, but they seem to have hit the sweet spot with the Microsoft Natural Ergonomic 4000, which hasn't changed since 2005. One of its most notable features is that it includes the full PgUp cluster—other (higher-end) Microsoft ergonomic keyboards omit those keys. I've typed on one, and it certainly feels like a solid peripheral, unlike some cheap keyboards and mice. Blogger Jeff Atwood gave it a great review back when it came out.
Right now Amazon's selling the "business version" of this keyboard for $30, which is a solid $10 less than the street price and $20 less than the MSRP. As a business keyboard, it's optimized for Official Business, like sending emails or data entry or filling out TPS reports, but I'm sure you can use it on personal time too. [Amazon]
We warned you yesterday, but if you're looking for what most people consider current Android champ on either AT&T or Sprint, it'll be $100 for renewals on Amazon. New contracts get it for $80—and if you don't care about Amazon, Wirefly is selling the HTC One for new Sprint customers for $50 plus fees.

Best. Keyboard. Ever.
Seriously. Quiet, comfortable, solid. My only quibble is that there's no right Win key.
