You might like to look at Microsoft's 'Surface' line of tablets, HiLo. They run Windows 10 and they all come with a USB port. The most basic model is the Surface 3 which came out about a year ago. Then there is the 'Surface Pro' line - which are tablets with the capabilities of 'full-fat' computers. I believe that the Surface Pro 3 line is still available - although probably not for much longer as the SP 4 came out in the US last month and in the UK this month. I should explain that the SP 3/SP 4 models are available in different variants graded according to how powerful they are (more powerful = more expensive). The basic models are probably perfectly adequate for the sorts of things that most of us do day-to-day (web browsing, e-mails, documents and probably music files). I'm not sure, without checking, how they stack up cost-wise with i-pads etc.
