Tethering a 7 incher
Been using a Kindle Fire with ICS on my daily commute for many a month now. Tether it to my lowly Xperia play and the phone easily lasts a day even though the xperia play isn't renowned for having a marathon battery.
Pretty super combination really. Fire is small enough to fit in my pocket and the ICS rom runs really smoothly on it (CM9 based). Tethering is seamless - I have a little widget on my home screen to turn it on and off with a single touch. Connects really quickly, no drops, recovers from loss of 3g signal , connection and data still works even when making calls. The only thing missing from the Fire is bluetooth imo - and possibly some meatier speakers. 8gb has been plenty. Nexus looks superior in almost every way. I'm very tempted.
