I just got mine and I highly recommend upgrading... I sold my 64GB/3G iPad2 yesterday for $450 very quickly. Here's the process to move your stuff over:
- Take a backup (not just sync) of your old iPad2
- Activate the new iPad over wifi
- Connect new iPad to iTunes and it will offer you to restore from backup, including the old iPad's name - do so
- Resync your photos, apps and other assets
