Apple’s new iPadOS includes mouse support for iPads.

I still try find out how to run database like Ms-Access or other database on my ipad. My office heavy use database system. How?

Not necessary, really depends on individual use case I would say. After all, iPad mini has the same OS as iPad air. It is just that iPad Air has bigger display,

IMO it really depends on the user, some prefer the palm size iPad mini for gamings, mobility, outdoor use, and etc, not to mention the mini is a great device for forums , I use the mini 5 for forums more than my phone...the viewing and typing experience is just fantastic..of coz I’d prefer using the iPad Pro for gaming/streaming at home/office, but still the mini win when it comes to use outdoor use..

You meant iOS widget ala android is it?

Not sure how useful is iOSiPad since I'm only using normal iPad 2018, screen too tiny to benefit from most of those multitusking features.

But iPadPro simply too expensive to be even worth considering.

this is why if S is still around. a lot of things we may not even be able to see. including ipad mini. and we may not even see iphone 6 plus becos S was highly against for non-one-handed phone.
