I decided to go another direction. I'm not a "power user", so I don't need a massive laptop. I DID enquire earlier here on the forum about what/how laptops people were carrying in their FJR. I didn't get much response.
What I wanted was a TANK BAG sized laptop. I still don't want a top case, so I found a tabletpc to fit in my Yamaha tankbag. In fact it fits in the map pocket. In fact, I can turn it on and use it while in the map pocket. Although in direct sunlight (while in the pocket) it is somewhat hard to see. The Fujitsu 1610 runs about 3 hours on the stock battery, about 6 hours on a 6 cell battery. I bought a 12 volt adapter so I can just plug it in and run it off the bike. Or I suppose I could have used one of those plug in 110 outlet converter jobbies. Oh well, the batteries are just for backup and the thing runs off car/bike/airplane power.
The touchscreen is small. Only 8.9 inches diagonal. It does have a full keyboard, but it is on the miniature side. Like I said, I'm not a power user. But I have a USB GPS, a USB DVD/R burner, it has Bluetooth, internal WIFI and I have a Mogo mouse for it that resides in the PCMCIA slot. Pretty nice in a 2.2 pound package. Enough to surf, do email, plot/plan trips, get the weather, etc,. Works well for me. I put it to use in Chicago while in class. Take notes right on the screen. Lots of uses. Carry it easily just about anywhere. Better have good bifocals, though!! :coolsmiley:
It might not be your cup of tea, but it sure works for me.
So to answer the original thread question, I don't use a backpack or a tail pack, I use a Yamaha tank bag to carry my laptop.
