After receiving my Scroll Extreme today (without any faults!). I've had a play and found a few ways to get access to the Google Play Store without any additional software.
1.) Goto Apps, Click "Scroll Apps", Open menu and select settings then click "More Applications"
2.) Goto Apps, Click Widgets, add the "Play Store" widget to your home screen
Below is my preferred way as it adds a direct link rather than a link to an app like the widget does, it also only uses up 1 icon space. Though its a bit more complicated
3.) From your browser go to the Google Play website, it will ask to open with browser or Play Store, open with browser (DON'T select "Use by default for this action") create a bookmark for Google Play, and with the drop down Add to Home Screen, this adds a link directly to the play store on your home screen without a widget. now when you click the bookmark on your home screen you can select "Use by default for this action" and it will open the Google Play Store directly without any hassle.
Sorry if its not very clear, if anyone has issues please say and I'll make it a bit more detailed.
