Since spell check seems to be a hot topic lately ...
After using my new Bold 9900 for a few days I have to say that I really like how RIM has implemented spell check for touch screen OS 7 devices.
Its very smooth, and when you touch the underlined misspelled word a list of options pop up in large font. You can then select the word you want by touch as well.
I also notice that the little blue text editing cursor in OS 7 looks very familiar.
I hope that the implementation in OS 7 is a preview of what we can expect on the Playbook.
