Depends on your needs: let/sublet appartment, pay lots of invoices, banking, keeping files, updating web? maybe a real computer.
For your smartphone, I would strongly recommend you a keyboard like the Stowaway Bluetooth Foldable Keyboard
. I have used for many years, now with a Samsung Omnia running Windows Mobile (only downside a little small screen the cell), and it is absolutely great, you type as with a real keyboard. Check about your OS. So, if one of you has the computer (we had an Asus 1008P), the other can write mails in the smartphone easily.
And finally, if you may think about a HD for your IPad, you take a look at Hyperdrive
. I have used a Colorspace O
and it was really good quality (although expensive), great to download memory cards (photos and videos) without any computer.
