Re: Which Tablet to buy ?
Just my 2 cents.
I would tend to go with the Asus Nexus 7 running Android as Mike recommended. For ease of use I would stay away from Apple for the simple reason that you have to run everything through an interface, it's a pain in the arse to have to wait for Itunes to do file transfers, for anyone used to PC or Linux Android just makes more sense. You know where your files are, you don't have to wait for a program to transfer them, network sharing is easy.
Steer clear of the Surface too, one major issue - you cannot charge from USB. May not be a biggie, but sometimes you may find yourself needing a quick recharge from a PC, you may find you're in a place where the current/wall outlet is different and need to buy a cheap local USB charger.
Jem's recommendation on the Dell is handy as you then have a machine that will talk directly to your Win machines with the minimum of hassle, although my past experiences with Dell have been terrible to put it mildly.
To tie things up. Please don't take photos with a tablet, they're awful (even the ones with good cameras are terrible), they're too unwieldly to hold up, you're relying on digital zoom which is .....well...digital and when I am trying to take a photo and some gob****e holds up a tablet blocking my view it takes all my will power not to grab it and smack it against his head until either one breaks. You can get a good camera with a real zoom for next to nothing.
As for photo storage, the non Apple ones are perfect. I carry one with my cameras when travelling. It's so easy, you've a 32gb micro SD in the slot, so when you fill up your camera card, hook up a USB transfer to a folder on the tablet and you're good to go again, no messing around with laptops or running out of space on the card when you need it.
As for connectivity they should all give good results on wifi no matter where you are on the planet. When wifi was less available I used to notice that in the middle and far east a lot of people still trusted WEP (and many still do), fire up Backtrack and within 2 minutes I could borrow some bandwidth for my tasks. If anyone here still uses WEP change it, even if you're on WPA change your key on a regular basis, if a not particularly tech savvy guy like me could borrow some bandwidth on either protocols imagine what someone with a little skill and drive could do.
