How about Cube iwork8 air ? “No space left for windows” this is common with 32GB memory and dual os (well without android there is not much free space either).
iwork8 seems fine, I’ll take a closer look
yes, 32Gb is a bit short but apparently the teclast has a bad partitioning
Keep in mind that all of the complaining you see on these forums is a result of the fact that it’s one of the few places to come to ask for help. If every satisfied owner of a tablet came and posted, this would look like a different place. I don’t think you can get a real idea of how widespread issues are from a forum like this.
