I agree.
In my university for example, in one of the rooms, I barely get a
signal - however, I am able to download at a decent speed. On the
other had, I noticed that upload speeds are directly proportional to
the signal strength. So unless you're doing heavy uploads, I don't see
low signal strength as an issue for regular web-surfing.

+1 to all the above.
Paul, if you do consider buying a USB wireless interface, might I
suggest going for one which has a detachable external antenna?
I can happily recommend any Alfa brand USB WiFi adapters - they have a
long range, are compatible with most distros, and are very affordable.
Personally I use the AWUS036NH which has a massive 2W output. Couple
that with a 5dBi or higher antenna and you can catch a signal from
miles away!
