I've held off from the last version of the IPP waiting for OLED, to replace my now almost 7 year old IPP 10.5 which has survived longer than I thought, and outlasted two Airs my spouse has had. Only way to go for a tablet.
Just used for media consumption mainly on the couch or in bed. Maybe the odd email.
I test drove a 12.9 a year or two ago, but was too unwieldy, mostly length and width wise. When hearing about the weight reduction, thought that maybe it would be better.
Playing with it at the store today, the weight is nice, but I think the physical length and width dimensions will still make it a tough go for my use, and thats irrespective of the additional cost over the 11.
Also thought I could maybe turn the 13" into a semi laptop and change some work flow patterns with the now metal keyboard and use it as a laptop on a desk when required, and on couch or in bed if required to use the keyboard, but reading here, the top heaviness is still an issue, it doesn't work as well as a MacBook when laying on a couch, and, the 13" and Magic Keyboard would set me back as much as MBP M3 Pro 14" refurb.
So it may just be the 11" for me.
