Flash is not the web. Flash support was the first thing I disabled from my N900 browser, and have been a lot happier ever since.

However, I'd definitely buy a larger N900. Bigger screen would be great for browsing a reading e-books, and the Maemo platform would allow me to take all our Midgard apps on the device so I could do stuff even when on an airplane (or at another country where 3G roaming is expensive).
