You will not find one this size, with this connectivity (Including inputs for guitar/bass/keyboard/mics), 10 hour battery life and with this sound.
On another note, we have the
iLine Cable Kit to connect mobile devices to the tools most modern musicians use. Amps, headphones, preamps, FX pedals...

Yes, it will work with any mobile device with a 4 pole input connector......
Even Windows computers/tablets/phones with a TRRS input can use this. Plus most Android devices.
So this thing will play with my Win8 phone? But the iRig stuff won't will it?
[edit]
I read up on it. Looks rather nice. Will it be available in music stores so that you will be able to hear it in person?

Yes, you should be seeing it in your local
IK Dealer location. If not, request it, they have a contact here where they can request one.
