I have a use
I have been waiting for years for a phone projector system. I have scoured guitar tablature sites for a decade and a half, collecting, editing then finally converting to an offline website over a thousand songs, hyper-linked and searchable by title, year, or artist, along with mp3's of every song in the collection, plus hundreds of TouTube how-to videos teaching general guitar techniques and many specific songs. Unfortunately I only know a handful by heart, even though I can play literally a thousand more when I have the words and chords up in front of me. My solution was to buy a 17" laptop to drag around with a charger and extension cord, in addition to my guitar. While that works, it is less than satisfactory. First I have to find a way to set up the laptop so that it is safe from drunks, dogs, children and just plain clumsy people, myself included. Then if other players want to join in they have to crowd around me, squinting over my shoulder to view the screen. And of course, if I'm away from a power source for any time, such as over a long weekend camping, then I either have to carry extra batteries or solar panels for the laptop. That just ain't gonna happen. I would love to ditch the laptop (it's old, heavy, has Windows' Vista, and fragile) and only carry my smart phone with me on my motorbike. The whole mess is about ten GB so I can store, (and share) it on a thumb drive or a flash chip. With a phone projector all I would then need is a surface to display upon, like a large sheet of white cardboard nailed to a tree or stapled to a fence, or propped up om a picnic table. I'm no Lang Lang but I've been ready for years to do the same thing on guitar as he did on piano with a smart phone. Bring it on Lenovo, make it affordable, and I'll be standing in line.
