I went looking for an affordable MP3 player for my girlfriend for Christmas, her Ipod's battery has issues keeping a charge, and she doesnt want/need another big model, since she never really listens more than an hour at a time, when she's at the gym.
So, I ran across the Sony Walkman 2G MP3 Player. So far, this thing is AWESOME. I've loaded some videos to it, and some music.
The display is crisp and clear and not blocky at all, almost HD quality output.
The sound is awesome on this model.
The price? $89.00 at Wal Mart.
The 4G ones are about 20 bucks more, but are VERY limited in where you can get them (although they can be ordered at Walmart.com)
I'm carrying a Sony Ericsson W580i Walkman phone and like it just fine, except that you can't fast-forward through tracks...just skip them.
That's a problem with me because I listen to radio broadcasts-turned podcasts, and I like to skip through the commercial breaks (which aren't real commercials anyway...they fill the breaks in with PSA's.)
Aside from that, it plays my files imported to iTunes from CD's in AAC perfectly, and the memory chip is a M2 memory stick that I can pull out and drop in my PC for faster file transfer. It pauses automatically for calls, and resumes when the call is completed. The M2 chips are available in sizes up to 8GB, and I COULD swap multiple chips if I wanted. Plus it has a built-in FM radio.
It's my temporary solution to my iPod's demise (hard drive.) I WILL replace the iPod eventually, but I've delayed doing so thanks to this device.
I think a bit more information is required. It sounds to me like something is hogging your system resources, which is probably why folders are slow and FireFox won't open. Are all your programs running slower than usual? Is it specific applications?
