The obvious major feature draw for the Eee Pad Slider is its slide-out keyboard. Offering a wide range of keys, it's got options for Home, Back and Menu, as well as a few keys to help you quickly conserve power if you're concerned about your battery life. Specifically, you can turn Bluetooth on and off, turn Wi-Fi on and off, and adjust the brightness.
Asus has taken the same route as other manufacturers when it comes to customising Android on tablets, and has included a carefully picked selection of apps and an original widget to make the Slider stand out.
The Asus Launcher is a slick widget that displays various bits of information, including the last website you left open, the currently playing music, calendar appontments, the weather, the date, and a slideshow of your photos.
It's a lot of stuff to cram into a widget, but it works really well thanks to a simple, no-nonsense design. We certainly prefer it to the utilitarian launcher widget included on the Lenovo IdeaPad K1.
As far as the apps go, the most useful is surely Polaris Office, given the nature of this tablet. It's a really good inclusion, with a slick, surprisingly powerful interface and options to create text documents, spreadsheets and presentations.
The word processor is particularly impressive, with tools for indenting, reflowing text, including media, tweaking fonts and loads more. In fact, we used it and the Slider's keyboard to write this entire review, with no problems in general (though a regular auto-save function would be gratefully received).
Cleverly, Asus is including an impressive cloud deal with the Slider. Asus' WebStorage offers unlimited online storage free for a year with the Slider. The app for it is easy to use, though it's a shame that you're unlikely to see it integrated into apps in the way Dropbox often is.
Amazon's Kindle client is included for readers, as is Zinio for buying and reading magazines, along with Press Reader for getting the newspapers right on your device. They're a killer trio of apps, all offering a great array of content, even if Zinio and Press Reader don't give you the flexibility in the publications that you get from Apple's Newsstand on the iPad.
Asus has also beefed up the built-in media options with MyNet, which adds media streaming both to and from the Slider.
The USB port on the side adds a few handy features, too. The first is that, like the Asus Eee Pad Transformer, you can plug in a USB mouse and control the tablet that way. If youre doing a lot of word processing/spreadsheet work, you might find this quite useful.
It also works a USB host for mass storage, so you can plug in USB drives or memory cards (with an adapter) and use the included File Manager app to browse and move files.
On top of all this are the usual Google apps, including the Android Market. Nvidia's Tegra Zone is also bundled, making it easy to find games, if you want. No games are included, which is unsurprising considering how this tablet feels more work-focussed.
