PVR's are all well and good, but usually tiny screens, and useless if you get somewhere, buy a DVD then have to wait until you get home to watch it.
I looked at all the PVR's and they're all much of a muchness, and I'd not touch them yet. (Apparently apple are working on a PVR with a 9" screen although it's not due until 2007 as yet). I've an iPod for the music side of things, and then...
I thought of my situation and did the following.
At home I have Sky+ (with a 120Gb upgraded disk) and a Panasonic DMR-E55 DVD-RAM Recorder.
So I bought myself one of
these. (£300 from Dixons at Manchester Airport for their display one, but can be got new for about £350-ish)
9" Screen, 2.5 hour battery life (up to 24 hours I think with the extended battery pack which goes underneath - £74 direct from panny). The standout features for me are;
1: DVD-Audio. Portable DVD-Audio player
2: Plays DVD-RAM and/or DVD-R - I can dump programmes from the Sky+ to DVD-RAM. Watch on the move, then erase the disks when back home.
3: 9" Progressive Scan High Quality Screen. You need to see the quality to believe it. Awesome screen. It doesn't output Progressive, but it definitely is progessive on the in-built screen. On purchased DVD's the quality is top top notch.
Most of the time I'm on the train, so I can plug into the train power. I also have an inverter for the car / plane so that's covered.
