科技达人的困惑 找一台能干正事的平板电脑  

My iPad is with me every night when I doze off to sleep
it entertains me on long flights and keeps me informed during my morning mute. But when it es to real work
the tablet fails me.
If I'm writing long emails or working on office documents
I want a larger screen
a roomy keyboard and the ability to easily juggle programs. The iPad doesn't cut it. Now
though
there are tablets that are literally standing up to the productivity challenge. Samsung's Galaxy Note Pro tablets are just hitting shelves
including a $749 model with a 12.2-inch screen and optional keyboard dock. Then there are Microsoft's Surface tablets
which are heavily promoted as the 'most productive tablets.'
But are any really as good as a laptop? To find out
I hid my MacBook Air under the bed and replaced it with four tablets paired with keyboard covers.
然而，有没有平板电脑可以真正和笔记本比肩的？为了探个究竟，我把我的苹果笔记本MacBook Air藏到牀下，用四台配有键盘盖的平板电脑取而代之。
In addition to the Android-powered Galaxy Note Pro 12.2
I borrowed o Windows 8.1 tablets
the Surface Pro 2 and Nokia's Lumia 2520. Microsoft has o tablet operating systems -- one for heavy puting and one for lighter work -- so I wanted to try both flavors. I didn't want to ignore the most popular tablet
so I paired an iPad Air with Logitech's Ultrathin Bluetooth keyboard cover.
I concentrated on the four aspects where my laptop continues to beat tablets: multitasking
text input
business-app selection and that delicate balance of speed and battery life.
Multitasking
I mostly toggle beeen email
a Web browser
a word processor
Skype and a Twitter app. My sofare needs may be tablet friendly
but I rely on keyboard mands
trackpad gestures and other shortcuts to maximize my multitasking.
When it came to moving beeen programs
the Galaxy Note Pro had some good tricks. I arranged up to four apps on the large high-resolution display (though o fit best)
and switched beeen full-screen apps by using the Alt + Tab keyboard shortcut.
It sure beat using the iPad
which displays one app at a time and requires you to press the home button ice to switch apps. The Logitech keyboard and its shortcuts didn't help much.
But it was the Windows tablets that let me multitask the fastest
locking apps side by side
or quickly toggling beeen them with keystrokes. Unlike the $499 Nokia
the $899 Surface Pro 2 has a 'full' version of Windows 8.1 -- with wider support for Windows sofare and greater use of the traditional desktop. I set up the tablet with my preferred classic Windows layout and could plug in a full-size keyboard and mouse
and up to four HD displays. That's important since the classic interface isn't optimized for a 10.6-inch screen.
Text Input
There was a tie for best keyboard. I was able to type 82 words a minute on the Surface Pro Type cover and the Galaxy Note Pro's keyboard cover
slightly down from my usual 92 words a minute. The Samsung keyboard was the closest in size to my laptop's
though my fingers felt most at home on the Surface's firm
backlit keys. (Both tablets also e with a stylus
which proved useful during meetings
converting my handwriting into text.)
I typed 80 words a minute on the Nokia keyboard case
and 72 on the iPad's Logitech cover. All of these let me type faster than on a screen. The keyboard cases did share one problem: They don't sit on laps very well. They all at some point did an Olympic-style dive off my legs.
App Selection
Each tablet except the Surface Pro es with productivity sofare. Samsung provides third-party apps that look like exact copies of Word
PowerPoint and Excel. The iPad includes Apple's Pages
Keynote and Numbers. If you want the real deal
Microsoft Office es preloaded on the Nokia Lumia 2520 tablet. (With the Surface Pro
you have to buy Office separately.)
The app selection gets more dicey when it es to job-specific sofare or accessing a pany neork. There are now iPad and even Android versions of business sofare
but you have to check first.
If your work relies on specialized sofare that hasn't been updated in a while
stick with the Surface Pro.
Speed and Battery Life
I expected the tablets to need Red Bull to keep up with my daily routine
including having 10 or more websites open at once
yet they held their own. That said
the Galaxy Note Pro was occasionally slow to launch and switch apps. The Surface Pro
with its Intel Core i5 laptop-class processor
was the peppiest.
But the Surface Pro's power es with a big sacrifice in battery life
not to mention size. The half-inch-wide
2-lb. Surface was out of juice after 5.5 hours
while the thinner iPad and Galaxy Note Pro streamed video for over nine hours
and the Lumia chugged along for nearly eight.
While the Galaxy Note Pro fared admirably
the Surface Pro did the best in multitasking
text input and sofare patibility. Still
I wouldn't prefer it over my MacBook Air
or any 13-inch Windows laptop. And as a tablet
it falls behind most petitors. The more useful for work these devices bee
the further they get from being really good tablets
which means it might take awhile before that perfect all-in-one device arrives. Until then
you'll find a tablet on my nightstand -- and a laptop in my lap.
