It improves the visibility a little bit and widens what you can see on your screen. But I find posting in landscape mode harder than in normal view. The keyboard occupies half of the screen, and makes reading forum posts harder when active. I also don't like the space between the buttons that occurs if you turn the phone to landscape mode.
Actually, we can't replace the convenience of typing with a keyboard and hovering via mouse cursor so it becomes mandatory if someone really wants to make posts with proper formatting, quoting multiple posts and answering in one post, or editing one post into multiple to answer each and every part separately.
We can use the landscape mode for reading purposes but I am okay with the vertical orientation with a little bit of zoom in/out if necessary and an occasional post without quoting or quoting the complete post.
If you are posting only with a phone, tough luck, Bitcointalk won't give you too much pleasure.
In case someone doesn't have a PC then your best friend is going to be an OTG adaptor with that we can connect a keyboard, mouse even gaming console with USB ports to Android devices.
That's a decent alternative, and I didn't think of that. I have heard of such Bluetooth keyboards but never seen one up close or heard anyone close to me owning one. Looking at the prices, they seem affordable, which is another plus.
I have one but it is made for a Samsung tablet but honestly, it doesn't give the experience of an actual keyboard. The ones shared look like actual ones so it may be the one.
Too bad that you can't connect an external mouse to the keyboard which would work on the phone as well.
Still possible, connect the wireless keyboard and wired mouse via
OTG then here you go the mini computer.
