I'm going to buy a Galaxy Tab and I'm hoping to find the answers here:
- Can I plug in a USB flash memory or an external hard-disk to Galaxy Tab via any USB Converter?
- Does Android 2.2 support VPN connections?
- Are Android applications free?
1 - No. There is a microSD slot where you can insert cards upto 32 GB in size to extend the memory.
2 - Yes - VPN support is present in 2.1 as well
3 - Some are free, some are not. Some are ad-supported.
