It depends on if the iPad Gen 1 has the features you want. Since you're just now getting it in Sweden then there's no telling when Gen2 will be available there.
But in the states I'd probably wait and just buy Gen2 which will at min have cameras and probably more memory.
I'm not a person who likes to sell stuff and also it wouldn't be worth the $120-150 hit when selling it for me 3.5 months later. I figure by Jan more details will leak, release late March, early April so 3.5 month from now...I don't have to have it so the wait is no problem
It's true if you wait for the latest and greatest you'll always be waiting to an extent. You need to decide on what features you want and can live with
If you wait for something that will have a few features more than todays model that will allow you to skip the next model then the wait would be worth it.
I bought my iPhone 3G a few months before 3Gs came out I didn't think it had enough features to justify the wait and used it and upgraded to the iP4
It's late in the cycle imo and I don't buy late cycle items unless there is a price drop which I don't think you're going to see..
You need to decide what's best for you or do like one guy said buy now keep it and buy the Gen 2 about 6months from now. That sort of keeps you refreshed midcycle. I think of the as iPad more of a buy every other release device than buy every year. Maybe buy every two years depending on how much of a user you are
On a side note I picked up a 4th Gen 8GB iPod Touch at Office Depot for $196(reg $229) out the door for my son

Brother works there and used his lowly discount(that took care of tax) but they had a $30 off coupon(had to be $150 or more) which really knocked the price down, they finally allow you to use coupons on technology items...
So thats just a heads up for you guys/gals who may shop there that you can get a good chuck knocked off tech items
I saw the ViewSonic GTab there and it wasn't too bad, alittle lag, nothing you couldn't live with and heard it was better with another firmware loaded from XDA but I think I may look at an Android tablet when they get 3.0 on it. I want to compare it and the iPad 2 before I make my choice
