I've gotta admit, the idea of being able to "jack in" a skill set, language, etc. at need has some appeal to me. [Neo]"Whoa. I know kung fu."[/Neo] Build up a whole library of data/skill chips, and break out what you need, when you need it. Granted that it certainly opens up a whole new world of personal/data security issues... No, I won't be doing it when Gen 1.0 comes out, guaranteed. But I'd be interested in that sort of thing.
On the physical end of things... well, at the moment, I'm running on all original parts, with only mild external assistance (I wear contacts to correct pretty bad myopia to slightly better than 20/20). I am, however, a diabetic maintaining fair blood-sugar control with meds who's struggled with weight issues for a long while now - the idea of hardware assistance for various bodily systems would be enticing, no lie. I can see some replacement or "upgrade" parts which I'd love to have, for a wide variety of reasons. And that's not even considering musculoskeletal and nervous upgrades for speed, strength, durability, physical sensors accepting additional types and ranges of inputs - biotechnic implants like those David Weber writes about in his 'Dahak' series ('Mutineer's Moon', 'The Armageddon Inheritance', and 'Heirs Of Empire', or the 'Ashes Of Empire' omnibus collection - the first book is available for free as an ebook at the Baen Free Library online) would be VERY nice indeed.
So, yeah, I'd probably end up with one or more "upgraded" systems, given the choice.
