sorry for the late response. anyways, so far i like the a2 but i still have yet to get used to it.
audiowise, it sounds great but i hear a slight hiss when it gets more silent. i dont know if thats unique to the a2, if its from the cd recording, or thats common to all daps.
with the functions, its like a swiss army knife. unfortunately some functions dont work well. the usb host for example is limited to certain devices and happens not to work on my digital camera. the lyrics are also pretty useless to english speaking users, because you cant find any lyrics on the search function, so youre left to type it all up (since you cant copy and past if theres commas in the lyrics). most features are really nice though, such as the ability to record basically anything. its quick and easy.
its a bit slow, but thats expected from something that could do so much. it also frequently freezes if you press too many buttons to quickly on certain functions but you can always turn it off and back on.
i havent got used to the joy stick and its hard to just press it. it often goes in a direction before you press it. its something you have to get used to though.
the video is great, unless you plan waching it in the sunlight. the direct sunlight makes it hard to see anything, but its great indoors. the screen itself is less scratch prone than the ipods, but for some reason, dust snuck in under it so im trying to find someway to clean under there.
umm. and its pretty big, especially with the case (which is nice. its not a leather jacket, but its nice) so the only way to slip in a pocket is without a case. even then, its thicker than my 3g 20g ipod with the iskin.
well thats about it for my rambling. and though all i have said has been pretty negative, i really really like this machine. i just highlighted some of its shortcomings that should be taken into consideration. its quite easy to use however, and preforms great. and like i said before, its a swiss army knife. i HIGHLY recommend it. it fits my criteria perfectly. the size is just a small sacrifice. but again, its a very very nice machine.
