This is mostly an inexpensive trial to see if something like the Xoom or other one much more expensive tablets coming out later this year would be worthwhile/useful/etc. So far, I'm pretty impressed but I do have a few thoughts.
1. I think Apple does have it a bit more "right" with the non-widescreen aspect ration screen. This might be less true on a device with a better screen, the G Tablet is much (and justifiably) maligned for a pretty crappy screen. Portrait viewing is not great with this narrow a screen.
2. Apple had better get off their ass or hope that Google has really effed up Honeycomb and won't release the source code soon. The G-Tablet is way faster than a stock iPad (perhaps not the 2) and I haven't even overclocked it yet. Also, once developers for Android get a little motivated to make more tablet-centric apps the race should get really interesting.
2a. Google had better get off their ass and finish it up already and get it out there. They've got manufacturers lined up and ready to go and they need to pounce on the incremental update that was the iPad 2. They also need to work hard with content providers like Netflix to bring that service in line with what Apple is already able to offer. Hell, partner with Amazon and tell Netflix to piss off if you want to but get a streaming paid media app on your stuff now.
3. Being able to add a sdcard is sweet. All told I'm into this for $330 shipped and it's got 32GB of storage, not too shabby. It is limited in how it can use the sdcard because it's running a hacked OS but even as bulk storage it's great. No idea why apply avoids this other than wanting to charge $100 for 16GB of memory. It's always stuck me as odd that the price point between the 16, 32 and 64 was an even $100 despite the memory bump being twice as much (better value?). What it really means is that Apple is making more $$ on the first two, probably.
4. Widgets rock. I don't get why Apple is so slow to adopt something like this. Even if Apple just did a few, in house widgets to start with it'd be to their benefit. The ipad with its pages and pages of apps all neatly lined up as individuals or folders just looks old-tech to me now. Again, once tablet focused widgets start rolling out for simple things like Twitter, Facebook and news type stuff it's going to be even more obvious how much of an advantage this is for google.
That's it for now, more later as I continue to tweak and do a little comparing with Ian's iPad next week.
