Clean Up Your Apps.
One of the first things you can do is go through and see if there are any apps that you can do without. I can almost guarantee that there are at least 5 or 6 apps on your phone or tablet that you can get rid of and give your mobile device a bit more breathing room to work with. Don't keep so many games on your tablet, just because they can take up a lot of space. There is nothing wrong with playing some Jet Pack Joyride while you are going to sleep (I'm quite fond of this myself), but when it comes down to crunch time you may want to get rid of something of the games you've not played in a while. For those iPad users, there happens to be an app available called Parallels Access which allows you to use any app from your PC or Mac directly on the tablet. The $80 annual rate may be a bit pricey, but for what you are getting out of it, it could be a great way to fill up that empty space left by the lack of games.
Time For Keyboard.
While it is nice to just type away on your tablet and feel good about it, there is nothing as comforting as feeling the keys against your fingertips. You are able to easily guide your fingers when you feel the keys, as opposed to just tapping on the screen. Not that it isn't responsive, but having an external keyboard or maybe a Touchfire keyboard accessory could definitely help deter you from making continuous typos. It will definitely make typing easy, feel more responsive, and can help you get more work done simply due to the fact that you wont be deleting every thing you wrote every 2 minutes.
A Second Monitor You Didn't Know You Had.
There are some apps out there that actually allow you to turn your tablet into a second monitor. The app will essentially confuse your Mac or PC into thinking that the tablet it just an external monitor. Perhaps you have an external monitor or two already. There is nothing wrong with adding another. Keep four different windows or apps up on four different screens. Contrary to popular belief, having extra monitors can actually help increase productivity. I should know, it helps me out!
All in all, there are many different ways to help get your tablet to where you want it to be. You don't have to necessarily get rid of every game you've ever loved, but cleaning up space can really help. The external keyboard can help a ton as well. The ability to have an extra (slightly smaller) monitor is also a big plus. It doesn't just have to be an Angry Birds machine anymore. So get to work!
