I have dipped my toe in the tablet pond. I have got an Advent Vega, a £200 Android tablet. Cheap price but the processor and screen are great.
I have upped the rom to include Android Market,and have gradually added more Apps.
Have had a couple of glitches where the wi-fi stopped, the screen rotation was 90degrees out, and reboots gave an error. Backup system works!
Why Android rather than Apple? USB port, SDcard, terminal.......
The Vega does not look as sexy as an iPad, but I am happy with its function!
