It's interesting reading through this topic, as there seem to have been a lot of tangents off on hardware related requests and general "I wish the tablet had x,y,z" rather than what the original thread was about "What cool things would you do?".

Here's a few of my coolness offerings... they're certainly not impossible or far fetched (some of them I'm already working on, some already exist but are just difficult for end users, and some are just crazy... or are they ;o) )

Home automation integration - Come on guys... everyone's talking about ir blasters... forget that, go big AND go home... what about, say, controlling the lights, stereo system etc from your tablet. Go one step further... how about when you get close to your house the tablet automatically associates with the local AP and turns the lights on for you if it's dark, adjusts the thermostat/etc. You could go one further and have it so that if you've got a cell/3g/whatever connection, it monitors your GPS location and does things like thermostat changes/etc when you get closer/farther from your house.

Same sort of lines, what about music integration? How awesome would it be to be listening to a set of MP3s or something on your tablet as you walk around, and when you get to your home computer/stereo/wherever and press a button on your tablet, your home stereo/computer/whatever just continues to play the playlist from your tablet at exactly the same point as you were just at, seamlessly. Same time, press a button on the tablet when you're leaving and have the opposite happen. Yea, sync and technical things involved, but that's what the development team is responsible for taking care of! And heck, while you're at it, same deal for videos...

I'm not sure if they're working on this in the latest carman or not, but about things like oil change reminders if you have one of those ODB interface things hooked up; you punch in a setting of how far/how long in time, and the tablet in the background silently tracks the data from your car and notifies you when it's time to schedule an oil change.

These tablets have so much potential for very cool applications, let's stop worrying about "oh the hardware is missing this piece" as inevitably hardware will change according to demand, and instead focus on the bigger picture of "what cool things" are possible/do you want to do.

Thanks,
