Actually, no. I don’t.
At least not yet. But I like the look of this MiFi contraption that’s on its way to these not-so-sunny shores. My wireless dongle sucks the life out of my Macbook pro’s battery, whereas accessing the internet via wifi causes barely a dent. Using MiFi as a dongle alternative would definitely increase my browsing time when on the move. Plus I could use other wifi-capable devices with it at the same time (e.g. my iPhone).
(I am such a shameless geek).
Just a pity that it’s being realised over here by 3. They’re not exactly known for their customer service, or more importantly for their 3G coverage. Pricing is yet to be announced. I’m assuming we’ll have to pay through the nose for such convenience…
