Having an Android tablet such as the ASUS Transformer Pad TF300T is great because of its 10.1″ LED WXGA screen and its NVIDIA Tegra 3 quad-core CPU. If you miss the feel of a QWERTY keyboard, this wonderful pad also has an optional full QWERTY chiclet keyboard mobile dock. This will transform your tablet into a netbook anytime, anywhere.
With all these outstanding features, the ASUS Transformer Pad also has custom ROMs developed for it by the Android development community. For example, there's the (unofficial) CyanogenMod 10 custom ROM, bringing Android 4.1.1 Jelly Bean, and there's the ICS-based unofficial AOKP custom ROM.
These custom ROMs are ready to be downloaded and installed anytime on your tablet. However, the common issue of these custom ROMs is that the tablet would lose its 3G features. In order to get this feature working again, you can flash stock firmware to your tablet and restore the tablet back to stock.
