Same as yourself Glen_Lee and TobyC, just can't do with reading anything but text messages on my android phone. Need a reasonable size screen to read threads and emails for that matter, but there again, I'm very much old school! If I have something important to say I usually attach a letter to an email and also send the letter hard copy; but I very much expect that I am in the minority! Apologies if I am going off topic.
Linux laptop using Firefox or 8" Android tablet using Opera (only use it for shaving forums and saves my passwords - everything else is Firefox too). Tablet is the same resolution as my phone, but is a lot more comfortable to read at arm's length
