I use my N900s fairly frequently to check TMO (and, now that I've gotten interested in the Jolla tablet, I'm browsing TJC with them as well). In fact, I have no trouble browsing a variety of my favorite sites. It is true that many modern websites are practically unviewable with Microb (or, for that matter, with any older browser or older machine). It is also true that these websites are insanely bloated pieces of craptastic web coding and extravagantly unnecessary multimedia. (My brother is on a satellite internet subscription, and lately he's had to be careful what sites he browses, as some web-pages will consume his entire month's download allowance in just a matter of minutes.)

So yeah, you really do need high-end hardware and high-speed internet access to comfortably browse many modern websites. But I've just gotta ask, do you really need to browse these websites in the first place?
