ASUS Eee Pad Transformer Prime & NVIDIA Tegra 3 Review
by Anand Lal Shimpi on December 1, 2011 1:00 AM ESTThe Display: Perfect
The original Transformer had a display that performed similarly to the iPad, but was far more reflective thanks to a fairly large gap between the outer glass and the LCD panel underneath. I excused the first generation Eee Pad in the display department because it was good enough and $100 cheaper than the competing Apple solution. The Prime reaches price parity with the iPad 2, and as a result it must meet a higher standard. ASUS doesn't disappoint - the Eee Pad Transformer Prime has the best display I've seen on a tablet to date.
The resolution is a Honeycomb-standard 1280 x 800. The 16:10 panel measures 10.1-inches diagonally, giving it a very similar surface area to the iPad 2's 9.7-inch 4:3 display. The increase in resolution more than makes up for the larger screen however, ASUS delivers 145 pixels per inch compared to the iPad 2's now quite-dated ~132 PPI.
It's not all about pixel density here, the Transformer Prime has better white and black levels than anything else in its class. It also sets the new benchmark for contrast ratio at nearly 1200:1. The huge gap between the outermost glass and the IPS LCD panel has been reduced significantly, in turn reducing glare.
ASUS also has a Super IPS+ mode that drives the display to a class-leading 683 nits. The Super IPS+ mode obviously draws more power but ASUS recommends it if you're trying to use your tablet outdoors. In our review of the PlayBook we found that 600 nits was really the cutoff for usability in sunny conditions, and ASUS easily exceeds that. It's also worth pointing out that while Super IPS+ increases black levels as well, the resulting contrast ratio remains the same.

Viewing angles are absolutely awesome. Yes this is the same ASUS that let us down with the UX panels but it definitely got the panel right when it came to the Transformer Prime. Fingerprints are still going to be evident on the display but they don't seem to be as bad as on the original Transformer, and they do wipe off easily. This time around ASUS bundles a microfiber cloth to aid in keeping your Transformer looking fresh.
ASUS, Apple and the rest of the tablet world are in hot pursuit of even higher resolution panels, the problem is yields on these small 1080p and 2048x1536 panels just aren't high enough yet. The Android crowd will have to wait, although Apple is apparently pushing very hard (and trying to buy up a lot of inventory) to deliver a "retina display" equipped iPad 2+/3 by Q2 next year. I'm hearing Q3/Q4 for everyone else and it's still not a guarantee that Apple will be able to meet its aggressive targets either at this point.

But what reason can you give for not getting an ipad? Too much software selection? Too great of an ecosystem? Too much wireless video streaming to your TV? Too high of resale value? Too easy to use?Curious minds want to know!

How about bad value for money? For the price of a 32GB Prime you get a 16GB iPad 2. It has roughly half the specs of the Prime: only 0.5GB memory, dual core processor v.s. quad core, lower resolution and screen size (which is REALLY annoying for watching 16:9 ratio videos, which is to say more than 1/2 shows/movies you can buy/download) and lack of expansion slots.In terms of software, iPad is smoother than android but at the same time you get a very limited browsing experience with iOS. I know HTML5 is the "future" but at the present is still dominant and will be for a while.
As for apps, whilst there are less app choice, It has a good range - you may have less choice in each department than iOS but you will always find apps suitable for your needs.
Build quality, at least for the prime, is also a lot better than the iPad's. Whilst both use aluminum instead of cheap plastic, the prime uses Gorilla glass rather than normal glass.
For $500, the transformer prime gives you a much, much better product. Apple products are very good and generally blows away low-mid range non apple products but when you compare apple's products to similarly priced alternatives, they just don't deliver acceptable quality for your money.
For example, a current generation MacBook pro 15" costs £1.6K. A HP 15" with virtually identical specs costs £800. The inclusion iOS does not justify a 100% markup on a windows PC. FOr £1.6k you can buy a laptop much, much more powerful than the £2k MacBook pro. The iOS may be better but is not worth £800. Furthermore to get full functionality out of a Mac you have to buy windows for bootcamp, which is another £120. By choosing a similarly priced alternative to apple products you "miss out" on an apple OS but gain much better specd products. I don't mind paying more for a better product but I expect the quality of the product to match the price and you just don't get that with Apple.

One criticism of the original Transformer was that the charging cable was too short. Have they addressed that issue with the Prime? If not - is a USB extension cable a reasonable solution to address a too short cable or is there an issue with the about of current being pushed down the cable to charge the tablet in a shorter time than the mini usb.Stas - Friday, December 2, 2011 - link
That is a fantastic screen! I'm very surprised and impressed.user777 - Sunday, December 4, 2011 - link
1) G3 USB stick testThere were a lot of questions regarding the G3 version of the tablet.
Is there a possibility to test any G3 USB stick on the Transformer Prime dock (example 50 USD/euro G3 usb stick from Archos G9)? It would answer all these questions.
2) Skype video call test
Skype is may be the most popular video app available for a lot of Android devices. Would it be possible to make a Skype video conference call test and confirm if the Skype app works with video on Transformer Prime?
3) MX Video Player test
I really like the MX Video Player which also has full support for multi-core processors, subtitles, mkv/m2ts/mp4/... file formats, etc. Is it possible to test MX Video player too?

The possibility to play multi format video files is indeed excellent feature of the Transformer Prime.Since the video file are quite large in size playing them from a home DLNA server via WiFi is important too (example Vuse torrent client DLNA server and playing by any third party DLNA client app like Skifta, iMediaShare, Bubble UPnP). Is it possible to test the DLNA video streaming of 720p/1080p videos?

for tablet/smartphone market, except Apple. Why? because it's so software/os dependent. With an open platform like Android/Window, it's very hard to harvest the extra resources.If you look at the PC market, the quad-core is for heavy gaming and server while the dual-core is the most generic CPU for every laptop/desktop out there. And that is with a matured market with matured OS and application.
I would doubt that Apple would go quad-core, but they are the only one can do it because they control both software and hardware. The rest? stick with dual.

Having a quadcore fast machine is good!However, there are not sufficient programs out there, really needing all that performance!
Most programs are smaller apps you can run with a single core running half the CPU speed!
And most games, 3D games run perfectly fine on a cortex A8 or A9 processor.
A pitty that software for Android is lacking behind!

That's the whole Asus Transformer Prime. It can use an integrated keyboard dock, to look much like a Zenbook. The hardware is similar.kamm2 - Monday, December 5, 2011 - link
"Scrolling is rarely as smooth as I'd like it to be via the dock's trackpad. Many times the gesture just won't register on the trackpad or the trackpad will detect my two fingers but it won't scroll."We have this problem with my wife's Eee PC netbook. It is very annoying. We are looking to replace her aging notebook and will not be buying one without scroll bars on the trackpad. The probably means no Asus. The trackpad is also hyper sensitive so it makes accidental touches while typing a nightmare. There seems to be no sweet spot when adjusting the sensitivity. This is in contrast to the trackpad on her first generation Eee PC which is excellent.
