I would also dispute the assertion that Internet Tablets (770 & N800) are "designed for developers" as that's not true at all.
Internet Tablets will work - mostly - out of the box as designed, but if you want to get the best out of them you need to put the time in and learn a few basic skills, however you don't need to be a programmer/developer - just someone willing to put in the required effort (reading, learning and do-ing - having a PC available with Linux or a LiveCD is handy too!)
Internet Tablets are not unlike Windows Mobile devices in this regard as even Windows Mobile expects you to learn an awful lot of cr@p about obscure apps/shareware that you need to download in order to get the full benefits out of the crippled OS. However with the Internet Tablets you can do an awful lot more hacking *yourself* than you ever can on a Windows Mobile device. For some, this means Internet Tablets are more fun, while for others it's too much like hard work and may put them off entirely (which is totally understandable).
