I don't understand the point of your post, since you already own the device and are not asking for specific questions.
But anyway, if you wanna know opinions, I had a Galaxy Tab, well, it was a gift for a relative.
To be honest I dislike Android quite a bit (which is odd because I'm a "power user") so it was hard for me to teach the relative how to use the OS. The lack of simplicity and the back, screenshot, options, home hard buttons made it real hard (I love the home button on iDevices) and overall widgets and else made it more confussing.
So I sold it before the 'Galaxy Tab 3 7"' comes out and bought an iPad Mini, and now it's real easy to teach how to use it, even via AirPlay and the AppleTV.
Now, Flash for me is dead, thankfully HTML5 is in, and flash based websites are usually just for people that know shait about technology and just wanted something "shinny" to show off, and the graphic designers that didn't want to think much.
If we leave aside the couple pages each month where a flash based video is shown, the odd page that still refuses to use new web coding "standards" and flash based gaming websites, then you'll see Flash is not really necessary.
Not justifying Apple since Jobs era and the obsession NOT to include it on iOS, but just saying, from my PoV, Flash is the cancer of the web just like Java is the cancer of the desktop.
About superior web browsing I don't know, to be honest for me it's the same on either iOS, Android or Windows (I happen to have a small windows-based touch notebook that I bought back in the day when I thought tablets were stupid hahaha!!!!), and it surely never feels the same to me, compared to a full-fledged desktop based experience, for whatever reason it might be.
Leaving that aside (both your points) I have to say the Galaxy Tab is a pretty neat device, it's obviously not as "powerful" as the 10" nor the Galaxy Note 2 (aka Exynos 4012-whatever based), but (and then here comes) I never felt like I needed power for Android since the market doesn't have the stuff I like on iOS, like Auria or any worthwhile synthesizer-app (since Android latency is a joke).
And I say that because I obviously used the tablet from time to time, even if I gave it as a gift, to test it mostly.
I don't think I have much to say more. I guess if you are in the market for a low-end tablet that is NOT the Kindle nor any Chinese creation (read: conceived by Chinese minds, not made because everything is made on china, obviously), the Tab 2 7" is quite a good choice, if you fancy Android.
Oh and as a closing argument, you are right, widgets are cool!
I still don't know if I'd use them that much, tho' as they waste a lot of battery (used to happen to me, back in the day when my smartphone was android-based), but I still see them appealing (e.g twitter, youtube subscriptions, RSS feeds, mail widgets).
