I've tried a bunch of keyboards. Hacker's Keyboard is great because it will be your Gingerbread or ICS keyboard in portrait and a full on keyboard when in landscape. You can literally go from chic to geek and back just by rotating your little gizmo.
Swype never got me and doesn't like to acknowledge vocabulary beyond the 4th grade level. You can also remove any keyboards that come with your ROM of choice after you install and configure another.
Power AMP is the only app for which I have ever forked out $5 and I'm so glad that I did. Looks great, sounds awesome (DSP and EQ that blows away Gingerbread DSP... and on FROYO!), and super intuitive (it resumes play whenever you plug in headphones and has it's own lockscreen with controls). I'd even pay $7.48 if they asked.
I'll have to check out the screen filter. I have come to appreciate the night mode in Go SMS Pro, since that's the only app I really use when I am hanging from the rafters in the dark. Except that I do sometimes check e-mail, if enough of them come through in a short time, and that is screaming white in me oye!
I love learning new tricks and tips whilst helping others. Thanks to you all!
