I love my Sensia, despite the 'niggles' with shonky software design/implementation - though hopefully these will be eventually ironed out in time. Agree that it's not terribly useful as a portable to carry about a lot. Even though you get a carry bag with it, you need to add the cost of a ChargePak and having this installed can be more of a liability, particularly when the radio locks up (fairly frequently I find) as you have to pull the chargepak plug to switch the radio off to reboot it.
I bought an Oasis Flow to cater for my portable needs - pretty rugged beast, includes a built-in ChargePak which seems to last for ages, is waterproof (splashproof) and seems more 'reliable' in keeping streams up than the Sensia. I use my Oasis in the garden, bathroom and workshop without the worry that it may get splashed/damp.
My Sensia is now permanently attached to my hi-fi to give me DAB, Internet Radio and access to all my CD's stored on my media server - it's in use all day, every day as I work at home. Has been reliable, apart from getting 'bricked' by the V2.4 update, but Pure support got that sorted by replacing the radio in pretty short order, so a big thumbs up to them.
