Best Buy Canada has a nice Black Friday deal
on Lenovo Tablets right now.
I'm tempted to pick up the M8 as a new portable reader. I have a M10 2nd Gen (4GB RAM, 64 GB storage) and really like it, but portable it isn't. I use an old Blackberry Playbook for reading PDFs on the go, but it's old and unsupported, and I wouldn't mind something with a few more tricks up its sleeve when I go out.
Even the M7 would be a substantial upgrade from the Playbook, but I'd rather spend the $30 for the bigger screen, faster processor, and extra GB of RAM.
