Microsoft’s plan to get its software running on every kind of device is coming together with the release of free versions of its Office software for Android phones.

The release is part of CEO Satya Nadella’s master plan to make Microsoft relevant again, especially in mobile where Windows Phone is barely able to get any traction. The company’s office software was already available on the iPhone and iPad, and now many Android users can download Word, Excel and PowerPoint apps directly from the Google Play Store.

“We are so grateful to our preview users, and with their help we were able to test the apps on over 1,900 different Android phone models in 83 countries,” wrote Kirk Koenigsbauer, corporate vice president for the Office 365 Client Apps and Services, on the Office blog. “During the preview, we heard from thousands of these users, and over the last few weeks we were able to incorporate a lot of their feedback into the apps we’re launching today. For example, we made it easier to connect to other popular third-party storage offerings like Google Drive and Box, as well as many usability adjustments to make it easier to navigate commands within the apps.”

Not all Android users will be able to download the apps however. In fact, only around half will be able to do so because the apps demand Android 4.4 or a later version in order to run, and they also don’t work on the Android M preview build. One gigabyte of RAM is also a must, and there’s also the problem of how much storage they take up.

More Bloatware?

The main annoyance for many Android users will be the sheer size of the apps. Word for Android is a 104MB download, and takes up a whopping 177MB when installed, and all those documents you save will only eat up even more space. As for Excel, that’s a 93.27MB download and takes up 168MB when installed, while PowerPoint is 91.07MB and unpacks to 166MB after downloading.

While those with high-end phones will be able to cope, those who use middle and lower tier Android phones will struggle to find space to keep them. To make matters worse, Microsoft says it’s partnering with 30 OEMs to have its Office apps pre-installed on their devices, including LG, Samsung and Sony Electronics. That might save users from going to the trouble of downloading the apps (which isn’t really much trouble at all), but it could also be annoying for many because OEMs generally make such pre-installed apps impossible to uninstall without rooting the phone. That’s a whopping 511MB of space that will automatically be taken up just to have Microsoft’s apps installed.

For someone using a lightweight phone such as Sony’s Xperia C (which only comes with 4GB of storage), that’s an awful lot of wasted, precious space that’s unlikely to win Microsoft many fans.
