Samsung Galaxy Tab - The AnandTech Review

So the battery life test is an interesting one, in that we don’t have a comparable tablet result yet - Anand used a modified version of the battery test in his iPad review and I haven’t yet had a chance to run the Viewsonic through the battery testing yet. I’m running these tests on my iPad, so I’ll update this page as those results come in.
But overall, the battery life is pretty good. The Galaxy Tab’s 14.8 Wh (4000 mAh) battery managed 9.75 hours on our web browsing test over WiFi. That outdoes the Dell Streak by an hour and a half, the Droid X by an hour, and the EVO 4G by two. Unfortunately, here’s the rub: Anand got almost an exact time out of the iPad, but he ran the same test with music playing in the background and email fetching every 15 minutes. I’m still running the web-only battery life test on the iPad, but I can safely say that it should outlast the Galaxy Tab by a decent margin.
Lightcycles. I kid you not.
To get a feel for battery life during video playback, I timed a looping 2GB H.264 encode of the original Tron DVD. The Galaxy Tab made it through four times over before giving up the ghost, good for 6:42 of video playback. This looks pretty poor in comparison to the 13.6 hours Anand got from the iPad in his 720p h.264 battery life test, but that video file was encoded to a lower bitrate, so it isn’t directly comparable. I’ll be rerunning the iPad using the same Tron file that we used this time around, and it’ll be our standardized HD video file for tablet battery testing going forward.
So without focusing too much on direct numbers, there’s only a couple of takeaways. The Galaxy Tab has pretty good battery life, but there’s not really any directly competing 7” devices to compare it with. The Galaxy Tab is more power efficient than the iPad due to the smaller screen, but the iPad has an absolutely massive 25 Wh battery. That’s the mobile equivalent of stacking the deck, so Samsung shouldn’t feel bad for losing out to the iPad on the battery life front.

because tablet software is made for the tablet while the software that is run on netbooks is developed for machines that are much more powerful with bigger screens and keyboards.
That's a big reason why netbooks are a crappy user experience and the experience on the iPad is a great user experience.

How about the Archos 70 or 101 internet tablets? Direct comparison is definitely possible with the Froyo2.2 update from their web page.tipoo - Thursday, December 23, 2010 - link
Do they have those for testing? I'm defiantly interested in those, with Froyo and potentially Honeycomb plus jailbreaking those look like solid contenders for a much entry lower price.Rick83 - Thursday, December 23, 2010 - link
Got a 101 for my parents for christmas...it's certainly not in the same league as the iPad and G-Tab, but at the price it doesn't have to be. And at least you get hdmi out and a usb host (with an extra adapter on the 70).If Archos could spare 5p for some marketing, they'd be a major player.... Sadly, their finances are a bit strained....And they're French :-O
Also, I continuously fail to see why people pay laptop money for sub-netbook hardware, just because someone went and threw the keyboard away. It's pretty ridiculous....At their pricepoints the Archos tablets are sensible products - slightly more portable than a netbook, and direct interaction UIs (ie touchscreens), while priced in the same region. The expensive tabs don't do significantly more, but the extra cost is just astronomical. Even 50% more, so in the 450-500 euro/$ range would be expensive....

It was a nice attempt on Samsung's behalf, but I knew I would be waiting for the Honeycomb 8.9" Tegra 2 tablets instead, like the LG Optimus Pad...rs2 - Thursday, December 23, 2010 - link
"So what then? It’s the software. Or, to be more specific, Froyo. It’s too similar to a smartphone right now, too much of the same experience repeated on a 200% scale."...and the iPad is the same experience as the iPhone on a 400% scale. You can't place the Galaxy Tab second to the iPad just for having the same problem as the iPad.

That would be true of the first version of the software. It was a bit of a kludge. Now we know that the iPad was actually conceived first, so you could say the iPhone is a scaled down iPad.But Apple did create a lot of new UI widgets specifically designed to take advantage of the larger screen real estate. Froyo doesn't have this. Apple released a new version of the SDK with an iPad emulator, Samsung had to put their own together without Google. I'm not holding out much hope for a good standard UI on Android either. Google is a great engineering company, but they miss out on the "soft" skills. Apple is good at both. I know Google has UI designers, but it doesn't appear that they listen to them very much. They seem to be more with Android over their other products, but that's not saying a whole lot. iOS looks clean and professional, Android does not.
I think in the end, people want a clean, polished product where the underlying technology isn't in your face, but is useful and makes it easy to get things done. MS is learning this lesson. Google needs to.

@rs2 - if you read my software section, I said exactly that - having a scaled up OS never held the iPad back, so it's not something I can hold against the Galaxy Tab. What I can hold against the Galaxy Tab is that there are basically no apps, first party or otherwise, that take advantage of the larger screen size, other than the three or four apps that Samsung put in afterwards (Mail, Calendar, Contacts, etc). Apple basically changed every core app on the iPad to use that screen real estate, and they had more than a few high profile 3rd party apps out for the iPad - ABC player, NYT, BBC, etc etc. I don't doubt that Google will get there, probably with Honeycomb, but until then, it's a legitimate problem.Rick83 - Friday, December 24, 2010 - link
Actually, there are both screen size and resolution variables that apps can read and adopt to, which only recently have been expanded to cover up to 10" (in 2.3) and 7" (in 2.2).So the issue with the apps is just a matter of time.
Also, tablets are much like TVs: consumption devices. You set the channel/insert your media and lean back. (Unless you belong to the group of idiots that mistake the devices for portable gaming systems...) In this scenarion UI scaling isn't as important as it may seem. Actually, even on my 5" 800x480 tablet, individual features are very small, and I prefer the easier reading on the big screen of the Samsung.
