HTC

"Future Proofing" a phone is difficult, because a manufacture needs to overspec the phone whilst still keeping it at a reasonable price.

HTC is notorious for underspecing storage on their phones. Other manufactures do not have the same problem.

Considering only 1% of android phones are capable of running ICS, I gotta blame it on the OS designer, not a reference hardware manufacturer.

In this case it is Google's responsibility.
