Any suggestions for a bag for a Nex-5n and tablet (plus a LITTLE of extra space)

I'm having trouble finding a smallish camera shoulder bag that can fit a Nex-5n (with 24mm zeiss) and an Asus Transformer tablet (a bit thicker than an iPad), but all I can seem to find are either large bags that can fit a DSLR + many lenses, or small bags for just a small mirrorless camera and perhaps a lens. I've been scouring the web but can't seem to find anything that's close to perfect.

I've currently got a Vanguard Up-Rise 38, and while it's a fantastic bag when using DSLR:s, the size is a bit too big for my current needs. Anyone got any tips for a small/medium bag that can fit the Nex-5n with lens on, and some additional small stuff (phone, tickets, memory cards) plus a tablet. Thanks!
