Probably not going to happen. People don't want keyboards and i don't see any carrier commissioning a qwerty phone for one carrier (verizon) worldwide.
I'd wager QWERTY android sales are unremarkable and low.
The WP7 keyboard is great and it's unlikely you'd use the hardware keyboard if it were there. Landscape and portrait.
My points to chinch, I know people say "well I have big hands and I don't like on-screen keyboards" but when we have phones that are 4.3 or 4.7 inches now,, even people with big hands can use them. It may just be all in the mind for people to get use to on screen keyboards if they never had one before.
If there was such a big demand for QWERTY keyboard phones, OEMs would be pushing them out left and right, but there isn't sadly.
I say try the on screen keyboard, you may surprise yourself. ATT's HTC Titan is a pretty massive screen, would be hard pressed to find sombody who couldn't use that on screen keyboard.
I understand the want for a physical keyboard for large hands, I was one of them. But with the advent of such advanced spell correction with touchscreens, it really is not much of an issue now. Heck the keys on my screen are larger than any I had on a physical keyboard. Plus there is much less to go wrong with a touchscreen keyboard.
Re: I want a QWERTY Slider Windows Mango 7.5+ Phone
I started this original post because I wanted to, hopefully, let VZW know that we W7P people are truly
alive and are waiting for a QWERTY Windows phone. I currently use a Samsung Alias 2 with a real
keyboard and love it. However I really want to upgrade to a smart phone when my 2 year contract is up in
April this year.
Maybe, just maybe VZW will respond.
