I still have my A90 and use it when I travel. Still works great - actually better than ever now that I have adjusted some things (turned off Aero in Win 7, switched anti-virus, use Chrome instead of Firefox most of the time). The extended battery I had went bad though, just ordered a new one. I recently got a Kindle Fire that I love that will also serve me well while on the go, although I still anticipate needing to take the netbook on some trips, where I might need remote access on some office things (tried it out on the Fire and it's really hard to get any real work done on it, plus I cannot access our payroll site on it) and/or where I might have to rely on wired access.
