yer but one advantage of the flash drive over portable is no moving parts so less that can go wrong especially if you take it everywhere cos hdd's can be damaged by even the slightest of knocks and bumps in some cases whereas flash memory is pretty much immune to knocks and bumps
and as you said its a lot more portable
well being one of the very few 64GB flash drives out there...you'd hope it'd be built with quality. 10 year warranty is great tho!
But i really don't think i need 64GB, even 8GB is way more then enough, after all i only use it for transporting school files aka projects, presentations, etc.
