I would suggest avoiding the 7750, and using only the 7250, because:
- The 7250 is benchmarked 5 times faster than 7750
- The web browser is 5 to 7 times faster due to faster CPU
- 32megs memory
- Smoother at multitasking (Alt+Esc)
- Improved keyboard
- More compact
- Bluetooth
- Less lag
- Better 1X chip. It's the new Qualcomm MC6500 (I believe)
- EV-DO upgradeable (2Mbps maximum, 300 to 500Kbps typical)
You'll thank me later. Try to avoid the 7750 dogberry. It works well, but it's slow.
