Well, I'm going to wait until the 7135 is on Sprint. By then, the price will have fallen, and maybe the speed issues worked out. I remember when $100 for it was a good deal. Then I saw $92, then $74, now $60. Patience will pay off, besides I have nothing to do with it until then.
I just bought the 256MB SD card from Ecost.com for $74, free shipping. I just got it today (took less than a week to AZ), loaded up my backup from my 128MB card, and voila! I still have 130MB available on the card!
Now I have room for more mp3's. I already have about 700 jpegs of family pictures (can't wait for an old friend to ask to see pictures of my family...). I scaled the jpegs to 320x240 so they load quick and are very small (about 20KB per pic). Mp3 files at 128Kbps are fairly large though, at 5MB per song, so those chew up memory in a hurry. Would also like to store some video on there as well, but still need to wait for better quality from Kinoma or Teal for the 7135. I have a 8 minute home video on Teal that takes 8MB that runs in sync, but is poor image and sound quality. Hopefully that will improve and then I'll need the 512MB card to hold more videos as well!
