I have to say -- the Peek is one of the best devices I've ever used. I can get all my email when I'm on trips w/o using a pricey device, plus yes...you can tweet with it. Such a great deal and a great gadget!
I'd definately like to have something more portable.
Though I love the giant screen on my Inspiron E1705.
However I'm finding it's filling my needs less these days because of the number of large files & photos I process on a weekly basis. I recently bought an iomega 500 gb desktop hard drive for more space; but that's inconvenient when I need to go back to last year's files......Need to figure out a set up that's more efficient.
I would like to buy in the near future a Nikon D60 & a digital video recorder.
