Chroot's still aren't as good. My N900 could run some games I made using PyGAME (all I had to do was something like sudo apt-get install python-pygame) and it was good to go - ran the game just as well as my laptop did, with acceleration. Beautiful.
Unfortunately my N900 screen broke for a second time last year, and I threaded one of the screws trying to replace it, so I too found myself looking for a replacement phone. Even with overclocking the N900 was painfully slow on complex websites, so I wanted something modern but with a hardware keyboard. I couldn't find anything except possibly the Neo900 (which didn't have an ETA at the time - and I wouldn't have been able to wait for anyway), so I decided that I would get the biggest screen I could find - the logic being that if I have to use a virtual keyboard I want it to provide an experience as close to a hardware keyboard as possible.
Hence, I now run a Sony Xperia Z Ultra with the Hacker's Keyboard. Obviously not as good as a hardware keyboard, but the screen size means the virtual keyboard can fit all keys I had on the N900 (and then some) and still have plenty of room to see the text-box I'm typing into.
The Xperial Z Ultra also has expandable storage so a chroot is feasible, and I admit I've used this phone much more than my N900 due to it being more practical for games, e-mail, taking pictures, etc. Sony also provide instructions on unlocking the bootloader. However, lacking a true GNU userland environment for the primary OS, along with lacking the ease of gaining root and lacking a replaceable battery) are things I really miss. I also hate how much of the bloatware cannot be removed, although it can be disabled. It is waterproof though, so it's got that going for it.
I nuked or disabled almost everything related to Sony and Google Play and installed F-Droid instead, and then proceeded to install Firefox Mobile, K-9 and APG, Xabber, TTRSS-Reader, VLC, Open Explorer, Barcode Scanner, Terminal Emulator, Cool Reader, Document Viewer, Aard, OsmAnd~, ScummVM, AnkiDroid, World Clock, VX ConnectBot, a few ownCloud-related sync apps... and of course Frozen Bubble, and now Android can do most of the things I would have used my N900 for.
