I use a cheap alarm clock to get up for work, bought 4 years ago at the knockdown price of $4.00 in your money, so cheap lol It does me, and I set it for my get up time, depending on what shift I'm on. It has a little black button to turn off the alarm I've set, all worked for these 4 years, but now its been Metro'd.
I now need to 'swipe' (left or right) across the screen to wake up, dammed annoying!!! as I preferred the button method.
Not only that, its projecting little boxes onto my walls and giving me the worst of nightmares?
Same can be said with a pad and pen I've used for years. All of a sudden Jesus said let there be an iPad, no stylus needed, just a soft keyboard and a swipe. Truthfully, I think the post-it notes are a better invention than an iPad. Simplicity at its best
