Curious what you guys think, as I need to get a pad. 
The only thing I know that I don't like is the proprietary nature of Apple. I do like their products though. Have a MacBook, PCs and cheap Android phone. I also noticed that iPads don't come with mini USB power like the rest of the world. So, another friggin cord..
 
Anyway. Samsung (10") or iPad (9.7") ?
 

It depends upon what you want to use it for.  Ipads are pretty cool for creation.  Tons of apps, esp. music apps.  But, I hate Apple (mostly for iTunes and demanding I change passwords once a week).  They also force you to buy new connectors ever couple of year, as you have noticed.  Besides, my wife already stole both pads I bought.  She likes them a lot more than I do so it ain't worth the fight and she keeps changing my apple account password then can't remember it. Even with all that, I'm thinking about getting the new large ipad pro for music and keeping it under lock and key. 
 
I bought a Samsung 12 inch tablet a few years ago w/ a nice chicklet built-in keyboard.  It is slow and stupid, but for writing and internet and mail it is perfect.  The atom processor won't handle SONAR or even music, but it comes with a full complement of slots and USB.  If I did want to play music I could at least put it on via USB, instead of loading it in via iTunes wireless.
 
And even 12.9 inches is small for some tasks - a stylus is needed. Get the biggest screen you can. 

I went the iPad route when I got one (its an old iPad).  I had an iPhone as one app that I wanted was only offered for the iPhone (Peterson strobe tuner).  More audio apps seem to be IOS.  My wife bought an Android tablet from QVC.  I'm not impressed with it at all compared to the iPad.  Different apps, update procedure seems clunky, etc.
 
However, I'm not an Apple PC fan.  Can't see paying 3 times as much for the same hardware.   

FWIW, iPad -
TONS of music-oriented apps AND hardware available that are made for or work with iOS devices.
Many of the iOS synths and FX can compete with some of the better VST plugins available for the desktop.
Updates are generally VERY easy to install on iOS devices, which is a big plus!

Apple's switch to the Lightning connector has been in the field for several years now, and it's established and capable enough that I don't see it going away anytime soon. I use all kinds of portable device in the field that require USB connectivity, and I can say with certainty that Apple's Lightning connector is MUCH more robust than the typical mini or micro USB connectors (especially the "jack" side, which is of course the most difficult to repair or replace).

I've been a Microsoft OS user (professionally and personally) since DOS days, and it's very doubtful that I will ever switch to a Mac for my primary computer. For portable devices, however, I've fully embraced the capabilities and convenience of iOS devices, and have never been tempted to jump ship for Android-based hardware : )

I went iPad to use for small remote recording gigs. Works fine for that. Also, the apps available for digital mixers, which I need in my line of work. Now that I've had one for a while, I like it.

It's looking like iPads in the lead.
 
I guess I should have mentioned that my main need/want right now is for maps, internet, netflix, travel.
Sorry I didn't mention that.
I hadn't even thought about music apps. go figure:) 
Thanks again.

Once you have owned and use it for a while you will never go back.  For all the things you mentioned they are great. Once you have also been using an iPad for a while you realise how clunky and simply ridiculous any Windows tablet actually is in comparison. 
 
If you have Apple TV you can call up stuff on your iPad and simply direct it to Apple TV and stream anything from the iPad to Apple TV and hence your TV screen and audio. I do this all the time. 
 
Also if you invest in a dock you can dock the iPad and use it as an instrument. Feeding Midi In and Out and Audio IN/OUT as well. The converters in a dock are much nicer than any built in iPad converters as well. I am running 4 synths on mine very well might I add and it sounds sensational. Just got PPG Infinite for it too. Only on iOS at the moment.  One very serious sounding instrument. 
 
There are some great remote apps. Studio One has a free one which controls either a Windows or Mac computer running Studio One.

This only runs on iOS as well. This is one very cool app. 
 
You can also get some very classy X/Y pad controller apps to for iOS and use them to talk to either a Windows or Mac machine.

I've never been an apple fan, but I did get an iPad. I just use it to read the news and books, none of my audio IFs work with it. Using it to read books there's no need for a cord, the battery life is pretty good. It's great for international travel - I have a library with me, but it takes up very little space in my backpack and I have wi-fi access.

If that is all you need, then Android will do the job, for less money.  Android is perfect for general computing, internet, etc.  I have a 5 year old Toshiba 10" that plays Netflix just fine over a wifi connection.  So I mostly just use it for Netflix, or my Amazon Kindle ebooks, or to play my MP3 collection.  Once connected to wifi, all the connected apps work fine.
 
But if you want to access the large number of music apps for iOS, the iPad would be the way to go.  It seems that is where all the music app development is being focused.

Thanks for pointing out the metagrid app. Nice.

The studio one app is one of my favorite things about that daw. Really want Sonar to adapt an app like that...
