HP's Mini 110 has received an almost negligible upgrade, adding so-so two colour options in addition to a more interesting HD video-decoding chip.
Colour wise the current "Black Swirl" option will be changeable for either "White Swirl" or a "Pink Chic" at a cost of $20. That's the price of standing out from the crowd, apparently. That said, while I'm normally an advocate for pink, I don't think it does the Mini 110 any favours and opting for that colour scheme will probably attract attention for the wrong reasons.
Less superficially, HP is offering the Mini 110 with a Broadcom's Crystam HD Enhanced Video Accelerator enabling HD video playback despite the limitations of Atom. Arcsoft's TotalMedia Theatre software is supplied with Mini 110 with the chip; suggesting perhaps that hardware decoding will only work using that. Still, while the ability to decode in HD is great in theory, I'm still not convinced it's that necessary a feature.
As ever there's no knowing if HP will bring this option to UK netbooks. Past experience would suggest you shouldn't hold your breath; we can but hope.
HP has also added a 1,366 x 768 pixel display option. Now we really need a UK launch!
