for Google's big tablet Nexus 10 is now ready for download at get.cm, providing Android lovers the chance to take the plunge on the extended world beyond the realms of JellyBean.

Anyone willing enough to tinker with the Samsung-built Nexus 10 can download the 163MB popular custom ROM, which will replace the stock Android 4.2 that Google deployed with the its first full-sized slate.

But the whole exercise is not for the faint of heart, blog site AndroidCentral.com warned, adding that the two early builds of CM10.1, based by its creators on the already open-sourced JellyBean, remain on the experimental phase.

That means installing the ROM in place of the stable and latest Google platform would likely be marred by bug issues and some share of headaches.

"You can probably expect a few bugs and incomplete or missing features in these initial nightly builds until things become a bit more stable," Alex Dobie of AndroidCentral said.

But as always, risk is accompanied by excitement as TalkAndroid.com endorsed getting this custom ROM for "Nexus 10 owners who are looking for some fun new features to play with."

The ROM was uploaded a week after the Nexus 4 version was rolled out, which now comes in six different flavours, according to PocketNow.com, to replace the LG-treatment of the increasingly popular Google smartphone that seems to be eternally running out of supply.

The CM10.1 for Nexus 10 must be regarded with the same care reserved for the Nexus 4 version as both custom ROMs are unstable, Engadget said.

"There's no word on when that final, polished 10.1 build will be ready for all Android devices, so for now, the keys to CM10.1 belong to a small group of privileged folks," the tech site added.

Meanwhile, forum users of Engadget have expressed conflicting views on the merits of wiping away stock versions of Android in favour of experimental and unstable ROMs.

"The only point I can see in installing a custom ROM is getting somewhat closer to stock Android but when a device already has stock Android it seems pretty pointless. Why ruin a good thing and get farther away from stock and voiding your warranty at the same time?" one of the comments said.

"I've been using CM10 nightlies for a while now ... and haven't run into anything that doesn't work. The ROM is great," another user fired off, in support of course of customising and taking more control of Android devices.
