Must admit to being very happy with my 901 linux
The battery life is stupidly long 4.5-5 hours easily
I personally don't have much trouble with the keyboard and much prefur the slightly smaller size and lower weight.
I currently carry it around in an old camera bag, but I'm considering a sewing project to make a belt pouch to replace this.
Heck just out of interest I just tried it in the side pocket of my trousers, it fits although a bit heavy.
The bootup time on the basic Xandros that comes on the linux version gas a boot time of 23 seconds
the wireless N is a bit problematic, takes a while to power up and connect to our network at work. (I've not timed it but I'd say between 30sec-1min)
The touch pad gets a little getting used to, the scrolling and zoom is great, but it took me a bit before I stopped accidently triggering "page back" on firefox
I've done no upgrading to it as yet, no even added an SD card.
Sorry, correction, I "lapped" the shiny area to the right of the touchpad as an experiment to reduce the shinyness and fingureprint attraction.
