I was just having this conversation with my coworkers this morning. It took me 3 years, but I finally found a use for a tablet. I am getting burned out on the constant cycle of patch and nerf that MMOs come with, and don't have the time to sink into console gaming. I have found that I enjoy the digital trading card games, and other phone/tablet based RTS genres, but that playing them on my phone strains my eyes, and causes my fingers to remain in cramped positions. As such, I ordered my first tablet yesterday evening.
However, the one thing that phones and tablets absolutely suck at is productivity, and I am currently attending college. My desktop, with its 22" screen and multitasking ability, rules for creating spreadsheets, writing essays, or even creating longer messages such as this post. However, the desktop stinks for the online portion of my math class as I have to lean forward to to reach past the keyboard for hand calculations, or try to do it against a clipboard or folder leaning in my lap. Either way quickly invites ergonomic issues.
Because of this I have a Chromebook. I can leave my desktop's keyboard tray pushed fully in, and bring my chair up against my desk. The Chromebook sits neatly to my left while my scratch paper is right in front of me. The only time I touch its keyboard is to enter solutions.
At first glance it seems ridiculous that I have 4 devices now, but each one of them fits a niche in my life. I don't see anything replacing the desktop soon as there is no other practical way to have a large screen and enjoyable input format, let alone true multi-window multitasking. However, I know that once my tablet arrives I will have little need to boot my desktop up anymore, perhaps once per week. I may even be able to do my online math homework on the tablet, but the Chromebook does this so well that I'm not certain it would be worth the hassle of finding a stand for the tablet.
